This paper addresses some problems concerning the geologic activity of sea ice and icebergs, as well as the influence of continental and shelf glaciations on the sedimentation in the Arctic Ocean during Recent and Quaternary times. Seasonal and circumcontinental zoning is clearly manifested in the sedimentation. The role of glacial material in the modern and older sediments was estimated. Mathematical statistical methods were employed for the reliable stratigraphic subdivision of Quaternary sequences and determination of main factors controlling their chemical composition. Silica content was proposed as an optimal parameter for the lithochemostratigraphic subdivision of Quaternary sediments. [ABSTRACT FROM AUTHOR] |
