Genetic sediment types have been identified based on a study of Core PS1599 collected from the eastern continental slope of the Weddell Sea. XRF analysis of 48 samples from this core carried out at the Vernadsky Institute of Geochemistry and Analytical Chemistry (Moscow) yielded the first comprehensive geochemical characteristics of all genetic types. Methods of correlation and factor analyses were used to outline geochemical associations of sediments and examine causes of their formation including the role of grain size composition. The results obtained have revealed fundamental differences between sources, mechanisms, and methods of transportation of sedimentary material for Holocene sediments, on the one hand, and Weichselian sediments, on the other hand.
