Hydrocarbon Potential of the Enisei-Khatangsk Region Within the Taimyr Autonomous District (TAD) and the Extent of Its Development (Russian)
The geological studies carried out on the territory of the Taimyr autonomous district of the Krasnoyarsk Krai during the period of 1930-1950 by the Glavsevmorputi subdivisions, the USSR Mingeo organizations and the institutes of the USSR Academy of Sciences (AS) show a considerable thickness of sedimentary deposits perspective for oil and gas, the availability of the Paleozoic salt-bearing sections, the prolongation of the continental tectonic structures into the water area of the marginal seas followed by the increase of the sedimentary deposits The TAD borders on three oil and gas bearing provinces of Siberia such as the West-Siberian, the Khatango- Vilyuisk and the Leno-Tungussk the limits of which allocate the Enisei-Khatangsk OGR and partially the Pur – Tazovsk OGR. (20). The total area of the oil and gas potential lands is over 550 th square km (13).
The history of the development of the Arctic segment of the Earth form the view of the plate tectonics
In the process of the disintegration of the Pungea supercontinent the deposition of the Arctic segment of the Earth began. The course of crushing and dragging of separate sections of the Lavrasia continent and the simultaneous joining it up with small microcontinents resulted in the formation of the Arctic ocean basin with its numerous depressions and uplifts – ranges (15,18). In the Devonian the riftogenesis caused the formation of the oceanic basin of the recent Arctic Ocean (21) . The Arctic basin continued to exist as gigantic gulf of the Pacific Ocean without any changes from the Devonian to the Late Jurassic (4).
The early period of the formation of the Early Mesozoic rift systems of the West-Siberian platform, North-West Europe, the North Sea, North America the Paleozoic median-ocean ridges of the Arctic Ocean and the Atlantic Ocean witnessed the downwarping of large territories and the formation of the Permian sedimentary basins of the sedimentation (19,21)
The splitting of the lithosphere followed by the formation of the abovementioned rift systems ,the formation of separate microcontinents separated from the continental platforms by the foredeeps was observed in the Triassic (19).
From the Late Jurassic to the Late Cretaceous there was observed the formation of the ocean crust in the Makarov and Kanadian cavities.
The extension of the territory of the East-Siberian depression in the Upper Jurassic and the Early Cretaceous resulted in the formation of the East-Siberian lithospheric plate, and the spreading of the continental Taimyr block-microcontinent was followed by the formation of the Enisei-Khatangsk trough. The formation of the typical Hertzianocean results from the downwarping compensated by a powerful sedimentation (10).
