Scientists have found traces of flood 6500 years ago, inundating Siberia

Siberian scientists have shown that about 6.5 thousand years ago in Western Siberia a catastrophic flood caused by the breakthrough of lakes in the Pamirs, and found evidence for a possible recurrence of such incidents in the future, according to RIA Novosti, Institute of Petroleum Geology and Geophysics (IPGG) SB RAS Sergey Guskov.

According to him, the study of bottom sediments of lakes Chany system in the Novosibirsk region were found shell of one of the simplest types of marine organisms — foraminifera, which can not live in fresh water and it quickly dies. Radiocarbon dating, made by accelerator mass spectrometry at the University of Arizona (USA) showed that the age of shells — from 6.4 to 6.7 thousand years.

In the past and now lives foraminifera species found in the Aral and Caspian seas. To explain how marine organisms could enter the northern freshwater lakes, scientists IPGG proposed and confirmed the new theory of the geological processes that took place in Western Siberia.

Andrei explained that all existing theories paleogeographic water connection between the south of Western Siberia and the Aral Sea in the Quaternary period (2.5 — 1.8 million years ago), there was only during periods of glaciation. Then, before the "dam" of the West Siberian glacier there were huge reservoirs which overflow spills over the side of the watershed in the Aral Sea. However, these processes could lead to skidding of microorganisms from the Aral Sea in western Siberia, in which case they would have to move against the current.

According to the authors, the water from the Aral Sea with foraminifera penetrated the West Siberian Plain, together with the anomalous power and strength of the water flow, coming from the Pamir Mountains along the Amu Darya valley. This stream perehlestnul and blurred even Aral-Irtysh watershed height of 126 meters. Confirmed this hypothesis found for this watershed — in Turgay hollow — sinks of the same species of foraminifera.

Interviewee of the agency said that a further study of bottom sediments of the Aral Sea flood catastrophe theory confirmed: one of the layers had clear signs of severe erosion.

The age of this layer is almost the same as the time of appearance of foraminifera in the Lake Chany. This means that come down from the mountain stream captured and brought to the West-Siberian plain water, the Aral Sea with bottom sediments and microfauna.

Andrei pointed to other signs of giant superpavodkov. For example, the age of a sea shell in the Aral Sea on the carbon analysis is about 20,000 years, and the age of the sediments in these areas has not yet been found — that is, in areas where shellfish are found, the sea was not. This could mean that the gigantic superpavodok 6500 years ago was not only in these areas, and perhaps he is again, the spokesman said.
