Abstract. Abstract. Objective of the study is to create a conceptual model of dislocation zone formation in the Western Donbass under conditions of strata movement and separation along the transform fault of the sub-meridian strike, and transtension, which causes a pull-apart shift with subsequent development of domino-type structures due to activation of the left shift. The author presents results of tectonogenesis mechanism analysis and morphometric and morphostructural studies of deformation processes, which participate in formation of modern coal-seam morphology and plans of natural methane-content in geological site of exploration in the Svidovskaya Mine. Within the coal seam, a zone with low natural gas-content of the Northeast strike was identified, which is caused by presence of tectonic belt in the rock mass formed by a series of low-amplitude tectonic disturbances, which are morphologically expressed by the shifts: the left Riedel shears R1.
Keywords: Keywords: Western Donbass, transtension, pull-apart, ramp valley, antithetic fault, Riedel shears, methane content.
