The depth of the new cave is only 4 meters more than the previous record-breaking cave.
Australian scientists just a few days ago discovered the new deepest cave in Australia. Geographically, this cave is located on the island of Tasmania and is part of the Niggly-Growling Swallet cave system. The depth of the new cave, which was named Delta Variant, is 401 meters, which is only 4 meters more than the depth of the previous record holder, Niggly Cave, ScienceAlert reports.
A group of researchers prepared for this descent for six months, and the descent itself took 14 hours. According to scientists, the new discovery provides an opportunity to better understand the natural processes that occur in such deep caves. Also, such studies provide an opportunity to better understand how the Earth's climate has changed over millions of years.
Although the recently discovered cave is the deepest in Australia, it is still the deepest cave, 2.2 km, located in Georgia.
According to scientists, such caves appear in karst geological formations. Here, the rocks are mainly composed of limestone, marble and dolomite. The flowing water over a very long period of time washes away the rock and such caves appear.
Karst also consists of tiny fossilized microorganisms that have accumulated here for millions of years. They left behind a limestone sediment that created relatively soft geological structures. As the water drains through the crevices in the rock, it dissolves the rock and forms a cave system.
“From a scientific point of view, caves are very valuable objects, as you can find cave formations in them, known as stalagmites and stalactites, these sometimes pointed structures protrude from the bottom of the cave and hang from its ceiling,” says Gabriel Rowe of Newcastle University.
These cave formations are formed when water passes through the cave. As with cutting a tree, growth rings or layers can also be found in these structures. Analysis of these layers reveals what natural processes took place millions of years ago during the formation of the cave.
“By exploring such deep caves, we can unlock many of the secrets of climate change on Earth in the distant past,” says Rowe.< /p>
As Focus already wrote, the longest cave system in the world turned out to be even longer. The length of the corridors in the Mammoth Cave, which is located in the United States, is now 676 km.
We remind you that in one of the caves in Spain, scientists found an “art studio” of Neanderthals, as well as the remains of animals and people.
