Аннотация: The Kureika-Tunguska Composite Tectonic-Stratigraphic-Sedimentary Element (KTCTSE) is located in East Siberia. Geologically, it is confined to the homonymic basin inthe northwestern part of the Siberian Craton. The basement of the basin is composedof Archean-Early Proterozoic metamorphic rocks. The sedimentary cover is composedof Upper Proterozoic and Early Paleozoic predominantly carbonate rocks capped witha succession of Middle Carboniferous-Permian coal-bearing sediments overlain bythick section of Early Triassic tuffs and lavas. The entire sedimentary cover, especiallyits upper part, is saturated with mafic intrusive bodies. The maximum depth to the topbasement can exceed 10 km.The KT CTSE is characterized by a very low exploration degree. Rather scarceprospecting works for oil and gas have not yet yielded positive results. However,indirect data, such as numerous bitumen fields, evidence of the source rocks, etc. arepromising for the potential discoveries including large hydrocarbon accumulations.
