THE FEATURES OF NNESTRIKE-SLIP FAULT SYSTEM AND ITS CONTROL TO REHE FORMATION IN WESTERN LIAONING PROVINCE
Hong Zuomin(Regional Geological Surveying Team Liaoning Bureau of Geology and Mineral Resources)
The strike-slip faults in N20°E were extensively developed, they are arranged en echelon with clear cutting. Fault breccia, cleavage, mylonite, Scratch, slickenside, etc are found in the fault zone.Sections of compression and tension appear in alterante on the same fault.Three associated groups of fault of NNW,NEE and NWW were developped. Tensile room,appearing in tensile section of the strike-slip fault and intersection of the strike-slip fault with its associated faults and the early EW or NE faults, performed the erupting passage of ancient volcanoes and provided the places for depositing he volcanic elastics. And the vertical movement induced by strike-slip fault had caused the eastward extension of the Yixian basin where the Jiufetang and the Fuxin coal bearing strata were developed.
