Grain size, shape and roundness of rock fragments, texture, composition of bottom sediments from the Sea of Okhotsk are under study. These data are compared with parameters of modern lithodynamic conditions of the sea and genetic types of deposits are identified. These criteria are used for partition of Holocene and Upper Pleistocene sediment series and for identifying conditions of their formation. Dependence of structure of different genetic types of deposits on intensity of hydrodynamic processes, of terrigenous contribution, and on direction consedimentational tectonic movements is under consideration.
