shear zone

Purpose. The purpose of the paper is the reconstruction of the geodynamic development of the shear dislocation zone (shear stress fields) of the Krasnoarmiiska monocline (KM) of Donbas (Eastern Ukraine) and determining the relationships of their impact on the emergence of gas-dynamic phenomena (GDP) in coal sediments. Methodology. Methods of digital geological cartography, mining-geometric simulation, geological-structural analysis, and structural-geomorphological reconstruction are used for the analysis of structural-geological information.

Purpose. This study focuses on the analysis of structures and kinematics of the western closure of the Horlovka anticline to present a general development mechanism and to determine whether the structural complexity of the study area is consistent with a single regional stress field or not. Methodology. The kinematic and structural data available for the study zone have been studied. Further, fault data, including both the fault plane and slickenline orientations, and the sense of movement, have been studied by the kinematic analysis method of O.
