21.01.2022 This week, a slightly lesser-known site, Margate Caves, has reopened after being closed to visitors for 15 years. Campaigners have been working to save it from redevelopment since 2008, raising funds to preserve, restore and reopen it. The caves were formed from a chalk mine dug in the 1700s. The stone was extracted by hand using iron picks, whose marks can still be seen on the cave walls. Around 2,000 tonnes of chalk was hauled out and used to make bricks and cement for loca...l building work. Once this was completed, the caves were sealed again and left undisturbed until the 1800s when, so one story goes, they were rediscovered by accident by a gardener working for the landowner, one Francis Forster. #vatnajoskullglacier #geology #geochempet #chalkmine #newzealand Ref https://www.theguardian.com//worlds-most-spectacular-caves

16.01.2022 Colorized elevation map of a lakebed in New Jersey shows stripes of ancient sediment deposits. The deposits are tied to cycles of wet and dry climates throughout Earth’s history. (Credit: LIDAR image, US Geological Survey; digital colorization by Paul Olsen) Ribbons of blue the modern Raritan and Neshanic rivers slice across a landscape that’s key to understanding Earth’s deep-time climate cycles. This colorized elevation map captures a 40-square-mile chunk of an ancient ...lakebed in central New Jersey. The purple and gray stripes represent layers of sediment that were deposited horizontally in a huge lake, then tilted and beveled off by erosion so the layers could be seen in cross section from above. Looking down on the cross section, you can see ridges (purple) made of hard, compressed sediment deposited during wet periods. Erosion has eaten away at softer sediments (gray) originally deposited in dry periods. By studying the layers here and at a similar site in Arizona, Columbia University geologist and paleontologist Paul Olsen and his team identified a 405,000-year cycle between wet and dry climates on Earth that has remained unchanged for more than roughly 200 million years. #geol,ogy #earth #geologists #geochempet Newjersey Ref: http://blogs.discovermagazine.com//how-sediment-layers-r/

15.01.2022 Nearly pure silica, the canary yellow Libyan desert glass was famously used to make a scarab that is part of Tutankhamun’s pectoral. Image credit: Jon Bodsworth. Curtin University’s Dr. Aaron Cavosie and his colleague, Professor Christian Koeberl from Austria’s Natural History Museum and the University of Vienna, examined tiny grains of the mineral zircon in samples of Libyan desert glass. Zircons in the glass preserved evidence of the former presence of a high-pressure mine...ral named reidite, which only forms during a meteorite impact, Dr. Cavosie said. It has been a topic of ongoing debate as to whether the glass formed during meteorite impact, or during an airburst, which happens when so-called near-Earth objects explode and deposit energy in the Earth’s atmosphere. Both meteorite impacts and airbursts can cause melting, however, only meteorite impacts create shock waves that form high-pressure minerals, so finding evidence of former reidite confirms it was created as the result of a meteorite impact. The idea that the glass may have formed during a large atmospheric airburst gained popularity after an airburst over Chelyabinsk in 2013, which caused extensive property damage and injury to humans but did not cause surface materials to melt. Previous models suggested that Libyan desert glass represented a large, 100-Mt class airburst, but our results show this is not the case, Dr. Cavosie said. Meteorite impacts are catastrophic events, but they are not common. Airbursts happen more frequently, but we now know not to expect a Libyan desert glass-forming event in the near future, which is cause for some comfort. The findings were published in the journal Geology. #glass #egypt #geology #geochempt http://www.sci-news.com//origin-libyan-desert-glass-07204.

14.01.2022 Elevated Levels of Oxygen Gave Rise to North American Dinosaurs, Scientists Say Aug 22, 2019 by News Staff / Source A team of researchers from Rensselaer Polytechnic Institute and the University of Texas Austin has used a new technique to analyze tiny amounts of gas trapped inside 215-million-year-old rocks from the Colorado Plateau and the Newark Basin. Their results show that oxygen levels in these rocks leapt by nearly a third in just a couple of million years, possibly se...tting the scene for a dinosaur expansion into the tropics of North America and elsewhere. #dinosaur #Newark #USA #geology #geochempet

09.01.2022 Almost anywhere you turn in Israel, you’re bound to find fascinating geology or the remnants of ancient human history. Some of the best of both can be found where you might least expect it near the Dead Sea, one of the least hospitable places on Earth. Located in the western Judean Desert on the border between Israel and Jordan, the sea is an artifact of incredible tectonic activity, which also birthed the jagged mountains that surround one of the world’s saltiest bodies of water. The Dead Sea is one of the saltiest bodies of water in the world. Credit: Shutterstock.com/Dejan Gileski #deadsea #israel #geology #geochempet

08.01.2022 The strata, twisted to near vertical in their tumultuous early history, were formed before much complex life reached the land.’ Photograph: John Gilbey Laid down under deep subtropical seas, when the fragment of crust that would become Wales was still well south of the equator, these mudstones are more than 400m years old. The strata, twisted to near vertical in their tumultuous early history, were formed before much complex life reached the land, but a witness on this narrow ocean might have seen the active volcanoes of Snowdonia on the horizon, creating structures that still although eroded and diminished dominate the skyline today.

03.01.2022 According to legend, the Giant’s Causeway was built by the Irish giant, Finn MacCool, as a crossing to confront his Scottish rival. Scientists have an alternative explanation, and for the first time they have reproduced in the laboratory the process through which the causeway’s 40,000 near-perfect hexagonal columns were formed. Geometric columns are seen in a variety of volcanic rocks across the Earth and are known to form as the rock cools and contracts, resulting in a regul...ar array of polygonal prisms or columns. But until now, geologists had been unsure of the threshold at which cooling magma suddenly fractures into a geometric pavement. Yan Lavallée, professor of volcanology at the University of Liverpool and lead author, said: [This] is a question that has fascinated the world of geology for a very long time. We have been wanting to know whether the temperature of the lava that causes the fractures was hot, warm or cold. To answer the question, Lavallée and colleagues recreated the process in the laboratory using basalt cores drilled from the Eyjafjallajökull volcano in Iceland. The 20cm-long cylinders, gripped by a clamp at each end, were heated to more than 1,000C until they began to soften into lava. The samples were fixed at each end in a mechanical grip and cooled to test at what point they snapped. The basalt magma fractured at between 840-890C, the study found, suggesting that this is the temperature at which the Giant’s Causeway would have formed. #giantcauseway #northernireland #geology https://www.theguardian.com//scientists-solve-mystery-of-h

03.01.2022 Israel, located in the Middle East, has a semi-arid climate. It is still influenced by the Mediterranean Sea, which allows sufficient rains in the coastal areas during winter. But a mountain range, running north to south along the coast divides the country. Jerusalem sits on the top of this ridge, to the east is the most interesting geologic structure of the country: the Dead Sea graben. A graben is an elongated, relatively depressed crustal unit bounded by faults on both sid...es. It is caused by a divergent movement of the plate. The plate widens and becomes faults, which results in a downlift of the crust between two of the faults. Once it is deep enough sea water will flow in and the graben will become a new sea, slowly but continually widening. This is how the Atlantic Ocean started many million years ago. This geologic structure was first described in German, thats why the German term Graben (ditch) is used internationally as the geologic term. The numerous limestone and sandstone layers of the Israeli mountains allow the water to pour from the west flank to the east. Several springs along the Dead Sea form each an oasis. This allows several settlements in the Judean Desert. The country has huge limestone karst areas. The caves are around comfortable 20C warm. But unfortunately there is only one show cave. Very common all around the country are small natural caves and abris. They were mostly used during 3000 or 4000 years of history as shelter, housing, storage rooms, barns and churches.

01.01.2022 Saudi Arabia holds the worlds richest oil reserves located between two valleys A Saudi geological study revealed the existence of a geographical spot in the Kingdom, considered the richest oil reserve in the world, according to Professor Abdul Aziz bin Laboun, a former oil adviser at Aramco and a professor of geology at King Saud University. The Saudi expert said that the spot is between al-Sahba wadi (valley) and al-Ramma wadi south of Batha border, and is considered the wor...ld’s richest with natural resources. Both wadis are considered the world’s driest, according to their surface perspective, and carry between them the one of the world’s vast wealth of oil and gas. Bin Laboun added: This spot is considered the richest in the world with natural resources from gas to oil and it includes the Saudi Ghawar oil field which is the biggest land field, Burgan oil field in Kuwait, which is the second land field and the Safaniya oil field in Saudi which is considered the world’s biggest sea field. The geology professor further explained that beyond the two wadis there are more than 100 gas and oilfields in a number of Gulf countries, but mostly in Saudi Arabia, making the two wadis the world’s richest with oil and gas reserves. Experts estimate that oil reserves in this spot to be at 440 billion barrels, which makes it a huge amount in a very narrow geographical spot. #saudiarabia #geology #oil Last Update: Wednesday, 27 June 2018 KSA 18:32 - GMT 15:32

An illustration of the ice-filled crater discovered in Greenland. Photograph: Nasa/Cryospheric Sciences Lab/Natural History Museum of Denmark A huge impact crater has been discovered under a half-mile-thick Greenland ice sheet. The enormous bowl-shaped dent appears to be the result of a mile-wide iron meteorite slamming into the island at a speed of 12 miles per second as recently as 12,000 years ago. The impact of the 10bn-tonne space rock would have unleashed 47m times the energy of the Little Boy nuclear bomb dropped on Hiroshima in 1945. It would have melted vast amounts of ice, sending freshwater rushing into the oceans, and blasted rocky debris high into the atmosphere. #greenland #geology #geochempet ref https://www.theguardian.com//impact-crater-19-miles-wide-f
