Lishi fractural zone

situated between Ordos Basin and Shanxi Rise

is characterized by.en echelon fault system in its north section and compresso-shear structures in south section.The faulting of the north section started in Late Paleozoic and the system has the property ofsimasphere fault;the compresso-shear started in Middle Triassic and the structures are considered to be sialsphere faults. The fault zone is not in lithosphere but in the earth crust since'it does not separate active zone from stable zone but secondary struetural units within NorthChina Plate
