| description | The results of mineralogical and geochemical studies of terrigenous rocks of the Early-Middle Permian Reshetnikovka formation in the southwestern part of Primorsky Krai are considered. Based on the data obtained, conclusions are drawn about the geodynamic nature of the deposits, and the main sources of clastic matter are determined. It has been found that, in terms of their parameters, the sandstones of the formation correspond to arkoses and are petrogenic rocks that were formed by of geochemically “mature”, largely weathered parent rocks of sources areas. Judging by the mineralogical and geochemical features of sandy rocks, as well as the position of their composition points on discriminant diagrams, in the Early-Middle Permian time sedimentation took place in basins associated with the passive continental margin. These basins were intra- and intercontinental rifts and aulacogens. The sedimentation was mainly influenced by continental sources of supply – cratons and uplifted crystalline basement blocks, which framed rift zones. Acidic igneous rocks were eroded with minor participation of ancient sedimentary formations. |
