Mineralogical Characteristics of the Sand Fraction in Quaternary Sediments from the Southern Margin of the Chukchi Plateau, Arctic Ocean

Resumo

The paper presents mineralogical analysis data on very-fine- and fine-grained sand in the composition of Quaternary sediments in the southern part of the Chukchi Plateau. The associations and downcore distribution of rock-forming and accessory minerals in relation to other characteristics are considered. The established climatically controlled mineralogical features, i.e., periodicity of warmings and coolings, can be used to solve a number of genetic problems, stratigraphic subdivision of sediments, and paleoreconstructions.
