Quaternary Deposits and Geocryological Conditions of Gydan Bay Coast of the Kara Sea

摘要

A description of the geological and geocryological structure of coastal exposures of Gydan Bay is presented. The data on isotopic and chemical composition of ground ice, texture, and age of deposits are presented. Two generations of polygonal wedge ice are distinguished: the Late Pleistocene and the Holocene. The conditions of sedimentation, freezing, and denudation of deposits during the last glaciation and the Holocene optimum are determined.
