Mineralogical and geochemical properties of the “moraine” complex of Holozene sediments in lake Nizhneye (East Antarctica) as a source of new genetical information

Using a complex of mineralogical and geochemical methods, the basal sedimentary horizon (“moraine” sedimentary complex) in Lake Nizhny in East Antarctica was studied. The bulk chemical composition, microelements, rock-forming and accessory minerals, and carbon matter were analyzed. According to all data, the studied sedimentary deposits are volcanogenic in nature, at least partially formed due to explosive products of eruptions of Mount Erebus.
