Peculiarities of the modern stage of development of the Yingkou-­Khingan fault zone

The Yingkou-­Khingan fault (YHF) zone is distinguished and peculiarities of modern (Eocene-­Holocene) stage of its development are shown. High geodynamic activity of the zone is demonstrated which is displayed in the saturation with Pliocene­-Pleistocene plateau-­basalts, tectonic and seismic dislocations and occurrences of argillizite metasomatosis and polyelement mineralization. Three stages of its modern evolution have been distinguished: Eocene­-Miocene, Pliocene­-Pleistocene and Pleistocene-­Holocene. The role played by a reverse-­sense shear in the formation of the inner structure of the zone are shown. Modern dislocation structures are described whish are considered as indicators of reverse-­sense shear deformations. The evidences of the deep character of the YHF zone and its recent seismogeodynamic activity are given.
Keywords: modeling, evolution, wave tectonics, reverse­sense shear, inversion structure, synergy, seismicity, erosion.
