They find remains of a continent lost 250 million years ago | Chronic

A study recently published in the journal Gondwana Research Scientists from the Universities of Utrecht, Oslo and the ETH Geophysics Institute in Zurich have confirmed the existence of an ancient continent buried under Europe. According to geologists, the Grand Adria sank about 100 million years ago and its history is difficult to rebuild.

According to scientists, the limestone rocks that prove their existence began as marine sediments and were then dragged from the surface of the earth's crust as a result of tectonic plate collisions. erosion

The co-author of the study Douwe van Hinsbergen claimed that Grand Adria had a history "violent and complicated". The geologist from the University of Utrecht explained that this land mbad was separated from the supercontinent Gondwana, which was home to the present territory of Africa, South America, the United States, and the United States. Australia, Antarctica, Arabian Peninsula and Indian Subcontinent, 240 million years ago. and since then began to move north.

Already 140 million years ago, the continent was the size of Greenland and part of its territory was covered with a slight tropical sea, where sediments gradually accumulated to become rocks.

Grand Adria followed her "trip" until it breaks with what Europe is today. The latter happened 100/120 million years ago. The collision occurred at a speed of between three and four centimeters a year, at a rate sufficient to completely destroy its crust by about 100 kilometers thick, the rest remaining below Europe.

During this time, some of the rocks remained on the surface and became a witness to its history.
The difficulty of the discovery was above all that these remains were scattered in more than 30 countries.
