LITHOLOGICAL AND MINERALOGICAL CHARACTERISTICS OF BOTTOM SEDIMENTS INTHE NORWEGIAN SEA NEAR BEAR ISLANDS

The Late Pleistocene and Holocene sediments were obtained during detai led oceanographic works on the Eurasian continental slope in the Norwe gian Sea (the nuclear submarine ''Komsomolets'' wreck site, depth -170 0 m). They were formed as a result of pelagic sedimentation (''particl e by particle''). The signs of horizontal transport of sedimentary mat erials with turbid currents and landslides were not observed. Main sou rces of sedimentary material were invariable during Last Wurm Glaciati on and Holocene. Some differences of mineral composition of bottom sed iment high-disperse fractions were related to the change of input of t he matter, which was included in the sedimentary fluxes by erosion and differentiation of shelf sediment material.
