Scientists have found, when Britain has made a “geological” Brickset
MOSCOW, 4 APR — RIA Novosti. Britain ceased to be part of a “United” Europe is about 450 thousand years ago, when the waters of a giant glacial lake that existed on the site of the Dover Strait, broke through the narrow bridge of land, connecting Britain and France, said in an article published in the journal Nature Communications.
“The destruction of this strip of land, connecting Dover and Calais in the past, was one of the most important events in British history, which has a huge impact on the formation of the British nation even today. When the ice age ended and sea level rose, the valley was completely flooded, and Britain has lost the connection to the mainland. The event was PACSICOM 1.0, for which no one voted,” says Sanjeev Gupta (Sanjeev Gupta) from Imperial College London (UK).
How to tell Gupta and his colleagues, the history of this discovery stretches back to the mid 1960s, when geologists, engineers and workers from France and England began to prepare for the construction of a tunnel under the English channel, linking the island nation and “greater Europe” only in 1994 due to political differences among Nations.
When the scientists got the first radar pictures of the bottom of the English channel, they found many strange potholes with a depth of 100 meters, filled with gravel and sand, which had forced them to lay quite tortuous route across the Dover Strait. These underwater “holes” and other structures found on the bottom of the English channel, subsequently, has led scientists to suspect that the British Dover and Calais to the French in the distant past might gather quite a real land bridge, then collapsed for unknown reasons.
Gupta and his colleagues uncovered the story of the destruction of the “bridge”, not less dramatic than the real Brickset 2016, making three-dimensional maps of the bottom of Dover Strait and examining the structure of the rocks on the shores of France and Britain in those places where they found his remains.
How to tell the scientists, Britain was separated from Europe in two phases, about 450 thousand years ago, when most of the territory of the future of the island is covered with glaciers.
In the southern tip of what is now the Dover Strait, there was a huge lake of melt water, separated from the waters of the Atlantic ocean thin enough “dam”. It was a ridge of soft limestone rocks, much like those today who folded the famous white cliffs of Dover.
Undermining the foundations of
In a certain period of time the lake was full and water began to fall down the slopes of these mountains in the form of giant waterfalls. According to Gupta and his colleagues, the hundred-meter hole opened by the builders of the tunnel through the English channel, are the last and only traces of the existence of these streams of water falling with great speed and power down.
These waterfalls undermined the base of these mountains, and at some point in time the rock could not stand the pressure and was broken, with the result that there was a huge flood, stopuri valley, who was at that time at the bottom of the future of the Strait. The Geology of the Dover Strait indicates that the walls of the lake was destroyed only partially, and the water continued to accumulate within it in subsequent years.
After that, there was another catastrophic event that led to the complete destruction of the land “bridge” between Britain and France. Traces of this process were, as claimed by geologists, giant potholes-channels on the bottom of the English channel stretching approximately 20 kilometers to the West of the traces of the waterfalls.
What caused this collapse, scientists do not yet know its cause could serve as the second “flood” and earthquakes occur in this part of Europe. Soon the Gupta team plans to take samples of rocks from different parts of the former “bridge” to clarify the chronology of its destruction and determine what forced the British to make the first “Brickset”.
