Mud Pump is also a popular concept of a wide range of pumps. Different regions, habits, and ultimately the pump type will not be the same. The mud pump described in this entry is a pump type in most sense: Applied mud pumps in the field of oil drilling. In fact, some non-clean water pumps and mud pumps, such as sewage pumps and slurry pumps, are also commonly used when they are called.

Mud pump refers to a machine that transports mud or water and other flushing fluid into the borehole during drilling. Mud pumps are an important part of drilling equipment.

In the commonly used positive circulation drilling, it is to send the surface flushing medium—clear water, mud or polymer rinsing liquid to the bottom end of the drill bit through a high-pressure hose, faucet and drill rod center hole under a certain pressure. Cool the drill bit, remove the cut debris and transport it to the surface.

The commonly used mud pump is a piston type or a plunger type, and the crankshaft of the pump is driven by the power machine, and the crankshaft passes the crosshead to drive the piston or the plunger to reciprocate in the pump cylinder. Under the alternating action of the suction and discharge valves, the purpose of pumping and circulating the flushing liquid is achieved.

A mud pump (sometimes referred to as a mud drilling pump or drilling mud pump), is a reciprocating piston/plunger pump designed to circulate drilling fluid under high pressure (up to 7,500 psi or 52,000 kPa) down the drill string and back up the annulus. A mud pump is an important part of the equipment used for oil well drilling.

Mud pumps can be divided into single-acting pump and double-acting pump according to the completion times of the suction and drainage acting in one cycle of the piston"s reciprocating motion.

Mud pumps come in a variety of sizes and configurations but for the typical petroleum drilling rig, the triplex (three piston/plunger) mud pump is used. Duplex mud pumps (two piston/plungers) have generally been replaced by the triplex pump, but are still common in developing countries. Two later developments are the hex pump with six vertical pistons/plungers, and various quintuplexes with five horizontal piston/plungers. The advantages that these new pumps have over convention triplex pumps is a lower mud noise which assists with better measurement while drilling (MWD) and logging while drilling (LWD) decoding.

The fluid end produces the pumping process with valves, pistons, and liners. Because these components are high-wear items, modern pumps are designed to allow quick replacement of these parts.

To reduce severe vibration caused by the pumping process, these pumps incorporate both a suction and discharge pulsation dampener. These are connected to the inlet and outlet of the fluid end.

Displacement is calculated as discharged liters per minute. It is related to the drilling hole diameter and the return speed of drilling fluid from the bottom of the hole, i.e. the larger the diameter of drilling hole, the larger the desired displacement. The return speed of drilling fluid should wash away the debris and rock powder cut by the drill from the bottom of the hole in a timely manner, and reliably carry them to the earth"s surface. When drilling geological core, the speed is generally in range of 0.4 to 1.0 m^3/min.

The pressure of the pump depends on the depth of the drilling hole, the resistance of flushing fluid (drilling fluid) through the channel, as well as the nature of the conveying drilling fluid. The deeper the drilling hole and the greater the pipeline resistance, the higher the pressure needed.

With the changes of drilling hole diameter and depth, the displacement of the pump can be adjusted accordingly. In the mud pump mechanism, the gearbox or hydraulic motor is equipped to adjust its speed and displacement. In order to accurately measure the changes in pressure and displacement, a flow meter and pressure gauge are installed in the mud pump.

The construction department should have a special maintenance worker that is responsible for the maintenance and repair of the machine. Mud pumps and other mechanical equipment should be inspected and maintained on a scheduled and timely basis to find and address problems ahead of time, in order to avoid unscheduled shutdown. The worker should attend to the size of the sediment particles; if large particles are found, the mud pump parts should be checked frequently for wear, to see if they need to be repaired or replaced. The wearing parts for mud pumps include pump casing, bearings, impeller, piston, liner, etc. Advanced anti-wear measures should be adopted to increase the service life of the wearing parts, which can reduce the investment cost of the project, and improve production efficiency. At the same time, wearing parts and other mud pump parts should be repaired rather than replaced when possible.

This ultra-ancient palace was such an astonishing find when it first emerged from the dust in 2022, that the lead archaeologist was accused of "making it up". Found in modern-day Tello in southern Iraq and long thought lost, the Lord Palace of the Kings stood above the ancient Sumerian city of Girsu more than 4,500 years ago, and was previously only known through fragmented inscriptions discovered in the surrounding sands.

Uncovered by the Girsu Project, an archaeological collaboration led by the British Museum, today the palace is mostly mud-brick walls, earthworks and foundations, though 200-or-so cuneiform (wedge-shaped characters used in ancient writing systems) tablets found nearby yield detailed administrative records from the city. The Sumerians were one of humanity"s first known civilizations, who first settled around 4000 BC. Their city-states produced the world"s first written script, its first known legal codes and the first ever examples of brewing beer.

Excavating the site has been an arduous process, and lead archaeologist Dr Sebastien Rey had to contend with scepticism as well as difficult, dusty conditions and political upheaval. "Everyone basically told me "Oh no you"re making it up, you"re wasting your time, you"re wasting British Museum UK government funding"," he said. Excavations have also revealed Girsu"s main temple, in honor of Sumerian god Ningirsu.

The director of the British Museum, Hartwig Fischer, called the site "one of the most fascinating I"ve ever visited". "While our knowledge of the Sumerian world remains limited today," he continued, "the work at Girsu and the discovery of the lost palace and temple hold enormous potential for our understanding of this important civilization, shedding light on the past and informing the future."

In 1974, laborers digging a well in China happened upon a life-sized terracotta soldier. When archaeologists came to investigate, they eventually unearthed thousands of similar figures, standing in trenches. So began one of the most exciting archaeological discoveries in history.

There are around 8,000 pottery soldiers and archers, plus 130 chariots and 520 horses housed in three pits taking up an area of 215,278 square feet (20,000sqm). The sculptures are all painstakingly created, with unique facial expressions, detailed uniforms and treads on their shoes. Many were originally painted, although the pigment has faded over time.

In 1987, a series of burial sites were unearthed near Sipán, on Peru’s north coast. The most intriguing and exciting discovery was a tomb, which housed a wooden coffin, containing a skeleton. It soon became clear this was the body of someone important – he was dressed in a gold mask, holding a shield and wore a headdress and copper sandals. He’d also been surrounded by treasures, including gold bells, a gold and copper rattle and hundreds of gold, silver and ceramic offerings.

Now known as the Lord of Sipán, experts believe he was an important Mochican warrior-priest. He wasn’t alone in his tomb, either. Three women (most probably wives), a child, two men and two llamas were buried alongside him. Today many artifacts from the find are displayed at the Royal Tombs of Sipán Museum in Lambayeque, Peru.

In 1989 a beautifully preserved pink temple was discovered hidden inside a pyramid in the ancient Maya city of Copán in western Honduras near the Guatemalan border. Thought to date to the 6th century AD, the three-story structure was buried under mud, plaster and stone.

The wooded Maya site of Balamku, home to the terraced stone Temple of the Jaguar, was discovered in Mexico’s Campeche state by archaeologist Florentino García Cruz in 1990. Sadly, treasure looters had arrived before the experts, but luckily they’d not stolen the site’s greatest treasures.

Most extraordinary of all García Cruz"s discoveries were the site"s intricate stucco friezes thought to date from between AD 550 to 650. The ornate frieze in the Temple of the Jaguar, depicting a king and a series of complex patterns and symbols, was the largest Maya frieze ever to be discovered at the time at 55 feet (17m) long. Today, a guard stands watch over the temple and its precious artifacts daily.

The frozen remains of a body that is older than the Egyptian pyramids and Stonehenge was discovered by hikers in 1991 on the Schnalstal/Val Senales Valley glacier between northern Italy and Austria. It was later determined the Copper Age man – soon to become known as Ötzi the Iceman – was brutally murdered. His body lay preserved naturally in the ice for 5,300 years along with his clothing and equipment. Pictured here is a reconstruction of Ötzi, created using forensic technology in 2011. The landmark "wet mummy" is now displayed in a specially devised cold cell in the South Tyrol Museum of Archaeology in Bolzano.

This curious set of man-made caverns in eastern China, also known as the Xiaonanhai Stone Chambers, was discovered in 1992 by a local man named Wu Anai. He became intrigued by the many large and deep ponds in the area. So, using a water pump, he drained a pond which revealed the mouth of a cave. Curious villagers then proceeded to drain a series of other pools in the vicinity until an impressive complex of 24 grottoes was unearthed.

Though subsequent research concluded that the caves are man-made and thought to date back some 2,000 years, their purpose remains a mystery. Also unclear is exactly how they were constructed in the sandstone hills – reaching a height of 98 feet (30m) in some spots, their formation would have been no small feat. They include pillars and carvings of lines and symbols.

The ancient city of Zeugma was originally founded by a commander of Alexander the Great in the 3rd century BC. Yet these spectacular floor mosaics were discovered more much recently in the 1990s. However, in 2000, the Turkish government built a vast dam just a mile away from the archaeological site, which threatened to leave the area submerged under water. This triggered a desperate attempt to excavate and save as many of the mosaics as possible before they were lost forever.

Until 1994, Göbekli Tepe was thought to be an abandoned medieval burial ground. However, German archaeologist Klaus Schmidt discovered something rather more astonishing – vast limestone pillars set in circles. It’s now considered the world’s oldest religious complex, having been built between 9600 and 8200 BC and predating Stonehenge by around 6,000 years. Six temples have been excavated, but geo-magnetic surveys suggest there could be up to 20 more.

The megaliths of these circles were carved with lions, scorpions and snakes, and weigh up to 60 tons. It remains a mystery how the hunter-gatherers shifted them into position, but the remarkable feat suggests society in the 10th millennium BC was far more developed than we first thought. In early 2017, a report in Science Advances also announced the discovery of three skulls at the site, which had holes and carvings, suggesting they may have been hung on display and that bones were used to honor the dead at this intriguing place. In 2018, Göbekli Tepe was made an UNESCO World Heritage Site.

The live archaeological site of Historic Jamestowne offers a detailed insight into what life was like for the 104 people who established the first permanent English settlement in North America in 1607. Since 1994, when excavations began, the remains of the original triangular James Fort have been found, along with more than 1.5 million artifacts. Burial sites, wells, bread ovens, gun platforms and empty wine bottles have been unearthed, along with thousands of artifacts belonging to the indigenous Powhatan people, who had lived on the land for 12,000 years before the arrival of the English.

Hailed as the dinosaur find of the century, the chance discovery of a near-complete skeleton of a small predatory dinosaur in a rock changed the way we understand the mysterious creatures and evolution. Found by a farmer in northeastern China, it was the first fossil that showed evidence of a non-avian species having feathers with a clearly visible fringe of tissue around the body. Named the Sinosauropteryx prima in 1996, subsequent studies have confirmed the ruff on the chicken-sized fossil were actually early feathers and colorful ones at that.

Selinunte was an ancient Greek colony in southwest Sicily thought to have been established from around 650 BC. While some 15% of the settlement was already above ground, including its five-strong temple complex, archaeologists were keen to find out more about the settlement and its inhabitants. They have spent the past two decades excavating the site and have uncovered heaps of hidden riches so far. It is now Europe"s largest archaeological park.

It’s thought that, at its peak, up to 30,000 people lived in Selinunte. But the settlement was constantly fought over by the Romans and the Carthaginians and was probably destroyed during conflict in the 3rd century AD. During the ongoing digs, the most fruitful of which occurred between 2013 and 2015, archaeologists uncovered the remnants of half-eaten meals and half-finished crafts, thought to have been abandoned by panicked and fleeing villagers.

The discoveries have helped build a clear picture of what life in this ancient society would have looked like. Researchers have exposed some 2,500 deserted houses, traced streets and discovered what they assume would have been a kind of industrial zone, where potters would have worked. Around 80 kilns and pottery workshops have been discovered, plus pigments and ceramic fragments. Selinunte is open daily with guided tours available for visitors to learn more about the site"s far-reaching history.

What was once thought to be a natural hill on remote Orkney, in fact turned out to be a vast, Neolithic complex of buildings, covering more than six acres of land. After the nearby Ring of Brodgar became a UNESCO World Heritage Site in 1999, radar surveys were undertaken on the surrounding area and, in 2002, a geophysical survey revealed a cluster of sub-soil anomalies, indicative of a settlement. After excavations in 2003, the Ness of Brodgar was unearthed.

The huge discovery revealed a massive Neolithic site that predates Stonehenge with some of the buildings dating from 3300 BC. Excavations, which are still ongoing, have discovered walls 13 foot (4m) thick, 90,000 pieces of pottery, bones and tools. On selected dates it has been possible to visit and see archaeology in action. TheNess of Brodgar Trusthas announced the site will be open to the publicbetween 7 July and 17 August this year.

Archaeologists dubbed a site adjacent to a quarry in the Cambridgeshire Fens the “British Pompeii”, after unearthing a large 3,000-year-old Late Bronze Age settlement. The site first came to experts’ attention when a series of wooden posts were spotted jutting out of the clay in 1999, but the first excavation didn’t happen until 2004. These early digs revealed a sword and spearheads, hinting at an early settlement. At this stage, researchers still had little idea of the scale of what lay beneath.

Extensive excavations (the most recent was a 10-month dig starting in 2015) revealed more about what experts now deem the best-preserved Bronze Age settlement in Britain. From their multitude of discoveries, archaeologists were able to piece together the fate of this ancient village, and uncover some previously unknown truths about the Bronze Age people. Textiles, pottery and roof timbers (pictured) were all among the finds – the latter allowed experts to understand how homes in this period would have been built.

Animal bones and fish scales (pictured) offered insights into the diet of the people who lived here, while fabrics gave experts a glimpse into the settlers’ clothing. Archaeologists also have enough information to deduce that the village was destroyed by a fire some six months after it was built – the village’s ruins sank into a nearby river, which is why they remain so beautifully preserved. Though there may well be more excavations in the future, experts are now busy studying the treasures exposed in the last dig and the site remains off-limits to the public.

This vast cave in Vietnam’s Phong Nha-Ke Bang National Park was first stumbled upon in 1990, by a logger named Hồ Khanh who took refuge from a storm in its depths. Once the storm had passed, he reported his discovery to the British Caving Research Association (BCRA), who happened to be in Vietnam at the time. Unfortunately, he couldn’t manage to trace his steps back to the mysterious cavern. Then, almost two decades later, Hồ Khanh rediscovered the cave"s entrance while hunting and alerted the BCRA once more.

In 2009, experts began exploring the newly uncovered cave and were awestruck by what they found. At more than 650 feet (200m) high and spooling out for more than 5.8 miles (9.4km) Son Doong Cave (meaning mountain river cave) was declared the largest cave complex ever discovered. They found stalagmites that towered to 80 feet (25m) and that the cave had a weather system all of its own. In 2013, Son Doong was opened to the public on guided expeditions. In 2019, divers discovered an underwater tunnel connecting it with another enormous cave, Hang Thung, making it even bigger than previously thought.

In July 2009 an amateur metal detectorist uncovered unfathomable ancient riches in a field in Lichfield. Known as the Staffordshire Hoard, the vast war stash was the largest collection of Anglo-Saxon gold and silver metalwork ever found, comprising over 4,000 items. A major research and conservation project took place from 2012-2016 to analyze the items which were buried in the Kingdom of Mercia in the 7th century. Most of the objects are gold and martial, once belonging to elite warriors, and were made between AD 570-650. The treasures are currently on display at the Potteries Museum and Art Gallery in Stoke.

With its elaborate exterior, the Sri Padmanabhaswamy Temple in Kerala is a majestic sight – yet this is just the tip of the iceberg. Buried deep within the Hindu temple, in a series of six vaults, are untold treasures said to be worth billions of pounds. The contents of one chamber, named Vault A, remained shrouded in mystery for years, but after a legal battle it was finally unsealed in 2011 so an inventory could be taken.

Inside, it’s reported, a dazzling array of gold, silver and jewels was discovered, including sparkling rubies, diamonds and an 18 foot (5.5m) gold chain studded with gems. A sixth chamber, Vault B, remains locked and the former royal family of Travancore (whose ancestors constructed the temple) is asking for it to remain that way, believing it would be against tradition and faith. Legend dictates that a curse hangs over the tomb, meaning terrible things will happen to anyone who unseals its doors.

When laborers were renovating this former royal palace in 2011, they happened upon a treasure trove, tucked away in a storeroom underneath the building. Stuffed inside three boxes was a huge stash of gold and silver coins and ornaments, weighing in at around 300kg (661lbs). The hoard was most likely an offering to the gods and goddesses.

Dr Julian Bayliss first spotted a rainforest right at the top of Mount Lico in northern Mozambique using Google Earth in 2012 (pictured). Though known locally, the mountain rainforest remained virtually untouched by humans due to its remote location. In 2017, Bayliss flew a drone over the peak and confirmed the forest"s existence. Then in May 2018, he assembled a team to scale the mountain and explore the pristine forest. The expedition was a success and the team uncovered a string of new species from fish to frogs, including a previously undocumented breed of butterfly.

In 2013, a couple of cavers discovered a haul of more than 1,500 fossilized bones in a chamber deep in the Rising Star cave system in South Africa"s Cradle of Humankind World Heritage Site. When the skeletons were eventually removed, it emerged they were in fact the remains of a previously undiscovered primitive species of human. The species, which was named Homo naledi in 2015, is thought to have had an ape-like torso, curved fingers and brains around a third of the size of ours.

Further analysis suggests this extinct species of primitive humans, whose remains have only been found in this cave system near Johannesburg, existed 236,000-335,000 years ago. Quite why the remains were so deep inside the caves is puzzling, but one theory proposes that Homo naledi used the caves as a place to deposit the dead.

With its 365 magnificent steps and imposing height, the four-sided El Castillo pyramid (or the Temple of Kukulcán) at the center of the Chichén Itzá archaeological site is one of Mexico’s biggest tourist draws. In 2016, archaeologists discovered the incredible ancient structure was hiding a secret. Already aware that a second pyramid lay hidden inside El Castillo"s walls, experts performed scanning techniques and revealed a third.

Another, later dig at Vindolanda uncovered yet more riches. The most significant find was a set of rare iron "hipposandals", a kind of historic horseshoe. Of the four hipposandals unearthed, only one was damaged – the others remained in perfect condition. The artifacts are on now display at the Roman Army Museum in Greenhead, Northumberland.

Every year archaeologists at Vindolanda, a Roman archaeological site just south of Hadrian’s Wall in the north of England, conduct an excavation of a different section of the land and discover some incredible finds. In 2017, they found swords, writing tablets and shoes and, most impressive of all, a pair of leather Roman boxing gloves (pictured). These curious artifacts went on display in the Vindolanda museum in February 2018 and will be joined by others – the museum says it will take another 150 years to complete excavations of the entire site.

Thanks to declassified spy footage and drone photography, a lost city was unearthed in Iraqi Kurdistan. Built around 331 BC, the fortified city of Qalatga Darband is thought to have been established by Alexander the Great and is positioned on a strategically important route between Iran and Iraq.

The site was originally detected when experts watched declassified spy footage that was made public in 1996, but the area’s political volatility meant nothing could be done at first. In 2016 though, a team of Iraqi and British archaeologists, led by specialists from the British Museum, begun excavating the area. In 2017, they began to uncover terracotta roof tiles and remains of statues that show an adoption of Greco-Roman architectural styles. Further investigations are now underway at two nearby sites, including a fort that dates to the Assyrian Empire (9th to 7th centuries BC).

The Maya settlement of Tikal in northern Guatemala has been studied for decades, and it’s one of the best understood sites of its kind. Or so experts thought. In 2018, new technology called LIDAR (Light Detection and Ranging) allowed archaeologists to dig a little deeper. LIDAR involves lasers, which pierce through the forested land to the earth below. Based on how long it takes a beam to bounce back, scientists can map any hidden structures that exist beneath the ground. The findings were extraordinary.

Studies revealed that Tikal is some four times bigger than experts originally thought. They also uncovered a central temple that was previously assumed to be a hill. It turned out to be a pyramid that was a smaller-scale replica of one in Teotihuacan, Mexico which suggested close ties between the two centers. Later excavations also confirmed the previously hidden buildings were raised using mud plaster, instead of the traditional Maya limestone.

After a three-year excavation project, an ancient church was found in Beit Shemesh, around 19 miles (30km) west of Jerusalem, in October 2019. The incredibly opulent church, which had colorful and elaborate mosaics, was named the “Church of the Glorious Martyr”. Archaeologists discovered this after an inscription dedicated to a "glorious martyr", an unnamed VIP, was found at the 16,145-square-foot (1,500sqm) site.

A Greek inscription was also revealed that thanked the Byzantine Emperor Tiberius II Constantine for funding the church’s expansion. Tiberius ruled between AD 578 and 582, around 100 years after the Roman empire collapsed, but it’s likely the church was built a little earlier during the time of Emperor Justinian, who ruled from AD 527 to 565.

Understandably, the legend of Rome’s founding by twin brothers Romulus and Remus has long been considered a tall story by historians. Discussions about the legend came to the fore once again with the discovery of a 6th century BC stone sarcophagus believed to be the tomb of Romulus, uncovered under Rome’s Forum in February 2020. However, on inspection, no bones were found inside. It’s thought it was a shrine dedicated to the fabled founding father of the Eternal City.

Historians have long known about Falerii Novi, a buried Roman city just north of Rome, but it was thanks to a new mapping technique, advanced ground-penetrating radar (GPR), that more details were finally revealed. Academics from Ghent University, Belgium and the University of Cambridge, surveyed the 30.5 hectares of land by towing the GPR equipment behind a quad bike. The images they took revealed astonishing specifics about the underground city that’s just under half the size of Pompeii.

The oldest and largest known Maya-built structure was discovered in Mexico’s Tabasco state using remote-sensing aerial technology in 2020. Following excavations, archaeologists radiocarbon-dated the site and estimated it was built between 1000 and 800 BC. It’s thought the large rectangular platform, which was made of clay and earth, was used for rituals. Known as Aguada Fénix, the previously unknown site sits near the northwestern border with Guatemala.

The most famous prehistoric monument in Europe, Stonehenge, on Salisbury Plain, was erected in the late Neolithic period in around 2500 BC. The mystery of how and why the enormous sarsen stones and smaller bluestones were transported and erected here has fascinated people for centuries. But in June 2020 it was revealed that next to Stonehenge another intriguing circular monument, an enormous ring of ancient pits, had been discovered using remote sensing technology and sampling.

The newly discovered prehistoric circle was discovered at Durrington Walls, just under two miles (3km) from Stonehenge, and consists of 20 huge shafts, more than 33 feet (10m) in diameter and 16.4 feet (5m) deep. These structures would have been an engineering feat and seem to have been designed to create a circle around Durrington Walls henge (pictured here) and Woodhenge, another smaller prehistoric circle to the south.

Radiocarbon dating revealed the shafts to be 4,500 years old and from the Neolithic period. It"s likely that the same people who constructed Stonehenge built the shafts at Durrington Walls, which is now the largest prehistoric site discovered to date in the UK and where the builders of Stonehenge lived. This reconstruction shows the settlement in midwinter, with timber monuments (southern circle and northern circle), houses and western enclosures in the foreground.

Archaeologist Dr Zahi Hawass and his team began searching for a temple near the city of Luxor, on the west bank of the Nile, in September 2020. And they got a little more than they bargained for. On 8 April 2021, they announced the discovery of an entire 3,000-year-old city which had been buried under sand. Known as Rise of Aten, it’s thought to be the largest ancient metropolis ever uncovered in Egypt – the significance of the find has been compared to the discovery of Tutankhamun"s tomb.

Described as a "lost golden city", it dates back to the reign of Amenhotep III, between 1391 and 1353 BC, which was one of the most affluent periods in Egyptian history. According to the archaeologists who found it, the former town is remarkably well preserved, with rooms filled with objects including clay pots, tools for spinning and weaving, rings and scarabs. Thanks to mud bricks bearing the seals of King Amenhotep III"s cartouche, the archaeologists were able to date the settlement to this period.

The Egyptian government announced a series of significant new discoveries at Saqqara, a vast ancient burial ground south of Cairo known for its stepped pyramid, at the beginning of 2021. This included the incredible discovery of a previously unknown queen. Archaeologists unearthed the funerary temple of Queen Nearit, who was one of King Teti"s wives. It was discovered near the pyramid of Teti, the first pharaoh of the Sixth Dynasty who ruled between 2323 and 2150 BC.

Also found at the vast necropolis of Saqqara were 50 wooden sarcophagi (coffins), dating back to the New Kingdom period (16th–11th century BC) which were found in 52 burial shafts. Another of the most dazzling discoveries at the burial ground for the ancient capital, Memphis, was 100 ornately painted wooden coffins, some with mummies and artifacts, including amulets (good luck pendants), funeral statues and masks, that archaeologists discovered in November 2020 (pictured).

First-time detectorist Ole Ginnerup Schytz literally struck gold in September 2021 when he discovered a hoard of Iron Age treasure in a field in Vindelev – at almost 1kg it is the largest ever found in Denmark. The pre-Viking treasure, which contained huge gold medallions, coins and jewelry has since been dated back to the mid-6th century by experts at the Vejle Museum in Jutland, who carried out the excavation after Ole"s discovery. They believe it was buried by an Iron Age chieftain under a longhouse to either keep it safe in the event of war or as a sacrifice to the gods.

Now known as the Vindelev Hoard, the stunning treasure suggests that the area was a powerful center in the late Iron Age and one that had traded with other countries for some time. Among the gold was a much older coin from the Roman Empire, dating back to the time of Emperor Constantine the Great (AD 285-337), suggesting countries were closely connected through both war and trade. The hoard is set to go on display at the museum in February 2022.

A sprawling 1,500-year-old wine-making complex was unearthed by archaeologists working in Yavne in central Israel in October. It gives incredible insights into the role wine played in Byzantine society and beyond. Consisting of five wine presses and four large warehouses, the winery was capable of making two million liters of wine a year. The team also unearthed Gaza jars, used for wine storage in the region, and kilns for firing the clay vessels.

The sophisticated complex, thought to have been the largest in the world at the time, would have made a prestige white wine known as Gaza wine or Ashkelon. It would have been consumed by the local community, as a safer alternative to water, as well as exported. According to the Israel Antiquities Authority, the incredible find confirms that the region was at the center of a flourishing wine trade with wines from the Yavne factory exported to Egypt, Turkey and Greece, as well as possibly southern Italy.

The largest of the mosaic"s panels can be dated to the late 2nd to early 3rd centuries and formed the floor of a dining room in a Roman mansio – a hotel of sorts that offered accommodation, stabling and dining facilities for Roman couriers and officials traveling to and from Londinium (Roman London). Given the size of the dining room and its lavish decoration, it is believed that only high-ranking officers and their guests would have used this space.

While dense vegetation previously hid these settlements and prevented researchers from finding the monumental structures, they used lidar technology for the first time in the Amazon. By attaching the laser scanner to a helicopter, they were able to produce these images (pictured) revealing the architecture and layout of the once-lost cities.
