Composition of bottom Sediments of Lake Baikal Recovered Offshore of Station Sharyzhalgay of the Circum-Baikal Railway
Baikal sediments were investigated, which were recovered at a depth of 1250 m offshore of station Sharyzhalgay of the Circum-Baikal Railway. The deposits are represented by an alternation of pelagic mud and turbidites. The composition of turbidites indicates that the source of the material is mainly from coastal and shallow water areas of Lake Baikal. A specific sediment layer, previously observed in sediments of the study area, most likely is related to the earthquake of 1912. This layer could not be discovered in the newly studied deposits. Probably the layer has been eroded as a result of a later event, due to the high seismic activity of the study area.
