Abstract:
This paper is devoted to studies of clay minerals from two cores collected in the northern and central regions of the St. Anna Trough, the largest trough of the Kara Sea. Upper Quaternary glacial, glaciomarine, and marine deposits are characterized by various contents of kaolinite, chlorite, illite, and smectite. It is established that, from older to younger deposits, amounts of kaolinite and chlorite generally decrease, while those of illite and smectite, on the contrary, increase. A joint analysis of distributions of clay and heavy minerals over the section allowed us to refine position of sources for terrigenous matter and their temporal variability. It is shown changes in sources of supply were directly related to climate changes that occurred when passing from glacial to marine sedimentation environments.
