New Facts and Representations about the Geological Evolution of Lake Baikal (According to Research of the Deepwater Manned Submersibles 'Mir')1

摘要

This article—one of the results of a unique expedition of sub ocean manned vehicles "Mir-1" and "Mir-2" on the lake Baikal. The Author of the article took part in 10 dives to depths of up to 1600 meters, during which he for the first time discovered the ancient layers of grave! material. The origin of these layers was associated with wave-cut activity in the early days of filling the lake basin. These underwater terrace— good indicators of a four lap increase in lake level, which corresponds to the stages of melting of continental ice formations in North Asia.
