CHARACTERISTICS OF BOTTOM SURFACE SEDIMENTS OF LAKE BAIKAL AND RECENT SEDIMENTATION PROCESSES

The lithological map of the Lake Baikal water area bottom at a scale of 1 : 500 000 was first compiled based on results of analysis of materials from previous studies and annual field geological and geophysical surveys, and a set of laboratory studies made at VSEGEI (2015–2020). The paper discusses the genetic typification and patterns of distribution of bottom surface sediments, describes recent sedimentation processes of the lake basin.
Keywords: sedimentation, granulometric composition, bottom sediments.
