Abstract

This study represents a scientific synthesis of the results of authors’ investigations on the problem «Geological and chemical paleooceanography of Carpathian-Black Sea segment of the Tethys ocean». Examination of sedimentary processes, which took place within the ancient continental margin, allowed studying of the maim features of terrigenous, edaphogenic and biogenic sedimentation and identifying in the lithological record of Precambrian-Phanerozoic a series of anoxic events, with which a range of mineral resources is related in the region under study. Analysis of data on geological and geochemical nature of the present-day upwelling in the World Ocean and obtained results on the nature of the upwelling process in the Tethyan part of the Carpathian-Black Sea region in Mesozoic-Cenozoic allowed distinguishing among the existing sedimentary formations of marine (oceanic) range a separate genetic type – «upwelling formation», which is suggested to be introduced into the doctrine about the sedimentary deposits, and this new scientific direction in geological paleooceanography to distinguish under the term «upwelling geology» and consider it as an original part of the Earth sciences.
