PERSPECTIVES OF SEARCH FOR RAW HYDROCARBON AND SOLID MINERALS DEPOSITS IN THE EASTERN HALF OF PRECASPIAN DEPRESSION (AKSAI – NORTH MAKAT AREA)

Abstract

The possibility of identifying deep and ultra-deep raw hydrocarbon deposits and also the deposits of solid minerals in eastern part of Precaspian basin within Aksai-Northern Makat section totaling 70,000 sq.km. has been studied on the basis of the analysis of isodata, geological, tectonic, geophysical maps, mineral resources maps, specialized mineragenic studies, as well as new ideas on geodynamic development of Kazakhstan and, most crucial, taking into account theoretical and practical ideas about origin of abiogenic raw hydrocarbon deposits associated with formation of volcanic hydrogen, referring to the deliverables of gravity study and prospecting work, primarily magnetic prospecting. At the same time, a keen attention has been paid to the deep structure and morphology of Precaspian rift, providing significant impact on the deposits` formation. The analysis resulted with identification of, for the first time ever, several highly promising magnetic anomalies where new shallow, medium and deep petroleum and gas deposits may concentrate, including potential deposits of ferrous, non-ferrous, rare, rare earth and radioactive metals. A considerable effort has also been made to the perspectives of search for oil shale and light tight oil which are potential sources for multiple augmentation of the reserves of natural raw hydrocarbons.
