Abstract
Strike-slip fault structures have been identified with confidence in the vast area of the West<br>Siberian north and characterized in detail by the Central Geophysical Expedition. Various structural<br>paragenesis of strike-slip deformations ranging from drag folds arranged in an echelon manner and early<br>shear systems to linear suture zones of rock mass discontinuities in the sedimentary cover can be mapped<br>there. Strike-slip fault structures have been identified in a giant territory extending from the southern<br>border of the Yamal-Nenets Autonomous Area up to the polar latitudes, covering an area of over 500<br>thousand square kilometers and holding largest hydrocarbon deposits. The study of hydrocarbon fields<br>shows a significant impact exerted by strike-slip faults on the formation of hydrocarbon deposits, on<br>regularities in their spatial-stratigraphic distribution, on reservoir properties and sealing ability of rocks.
