New results of investigations of the composition of recent bottom sediments and deposits of tributaries in the area of Cape Ivanovskii, (north shore of the South Basin of Lake Baikal) are presented in the article.
Results show that the speed of recent sedimentation in this part of the lake is 0,8 mm y-1. This value agrees well with sedimentation rates measured in other parts of the South Basin before.
Diatom analyses testify that Holocene and Late Pleistocene sediments were recovered in sediment cores from water depths of 500 m near the shore. Here, bigger thickness of oxidized layer on top of the sediments is observed, compared to cores from deep water (approx. 1300 m), which indicates a smaller speed of sedimentation.

New data on the characteristics of Baikal’s turbidites are also added. Redeposited pollen grains of Jurassic and Neogenic age have been identified within the Holocene turbidites.
The mineral composition of the sand fraction of deposits of tributaries is mainly the same as of other sediments in South Baikal. However, additionally few grains of olivine ((Mg,Fe)2SiO4) and spinel (MgAl2O4) were found in some samples. The source of these minerals is the coastal rock formation of «Belaia Vyemka».
