| contents | An integrated (petrographical and micropaleontological) study of sedimentary cover samples dredged from the lower slopes of the Kuril deep-sea basin was carried out. Pliocene-Pleistocene sediments are mainly represented by tuffaceous sedimentary rocks (tuffites, tuffaceous muds, tuffaceous diatomites, tuffaceous silts, tuffaceous sandstones, etc.). Significant admixtures of pyroclastic matter, especially of volcanic glasses, indicates that sedimentation process was accompanied by explosive volcanism. The data obtained give evidence about intensification of tectonomagmatic regime within the region under study during Pliocene-Pleistocene time. By the beginning of Pliocene, a deep-sea basin with a well-manifested continental and/or island slope and a narrow shelf already existed. Pliocene-Pleistocene deposits accumulated in a cold well-aerated deep-sea basin under oxic conditions and downslope sediment transport. |
