PALEOGEOGRAPHIC CONDITIONS OF THE APTIC DEPOSITS FORMATION IN THE SOUTH WEST CRIMEA

Abstract

The paper considers the results of paleogeographic reconstruction of formation conditions of the aptian strata of the South-Eastern part of the Balaklava basin. The radiogeochemistry of the aptian sedimentary strata, mineral composition of clays and their microstructural features were studied.In conclusionthe predominance of southern demolition of terrigenous material is proved, possible rocks of feeding provinces are determined. The data of the study of the clay strata suggest their connection with the oil source rocks, which may be found in the shelf zone.
