GLACIAL MATERIAL IN THE KING TROUGH AREA (THE NORTH-ATLANTIC) - ORIGIN, AGE AND IDENTIFICATION CRITERIA

The rock material taken with the aid of the MIR deep-water submersible s, as well as that obtained by grab and drag sampling and coring was a nalyzed to show that, unlike the outcrops of the ocean floor, over the vast North Atlantic area this material was represented by the contine ntal complex rocks. This rock material is proved to be related to the iceberg scattering of the Quaternary glaciations. Independent data on the distribution and composition of sandy-alleurite grains in sediment cores also confirm the relation with the last glaciation. New cirteri a for the identification of iceberg material in pelagic sediments are presented based on the analysis of all the data.
