Facies structure and quantitative parameters of Pleistocene sediments from submarine continental margin of Wilkes Land and the Ross Sea (Antarctica)

Lithological-facies zonality of Neopleistocene and Eopleistocene sediments from Antarctic continental margin off Wilkes Land and in the Ross Sea has been described for the first time. Processing of respective maps and isopach schemes, compiled by authors, by means of volumetric method by A. B. Ronov gave an opportunity to calculate quantitative parameters of sedimentation for mapped types of Pleistocene sediments. We revealed the dominance of terrigenous sediments. In Neopleistocene they accumulated more intensively than in Eopleistocene. In Eopleistocene, vice versa, siliceous sediments accumulated wider than in Neopleistocene.
