Abstract

The Lower Priamurye geoblock (the first-rank structural element of the Amur plate) was distinguished based on the morphostructural data. This geoblock is affected by neotectonic right-lateral strike-slip displacements along northeast-striking transregional faults. Arc faults have been formed inside the geoblock due to the imposed stresses. The faults are geomorphologically expressed as a conjugate system of river valleys bordering four blocks with rounded habitus that are composed of Mesozoic-Cenozoic magmatic and folded sedimentary rocks. A vortex-like arrangement of the faults inside the blocks, and the right-lateral strike-slip displacements consistent with the direction of deformations along the northeast striking faults, indicate the counter-clockwise rotation of these blocks.

Keywords

Strike-slip zones, arc faults, rotational motions, rotation blocks
