Tan-Lu fault zone is a large scale fault zone characterized by polystage movement. It is started during collision between North China Block (NCB) and South China Block (SCB) in late Upper Triassic. The early stage (J₃-K₁) of movement known as left-lateral strike-slip which is associated with compression (early) and extension (late) is limited in inner NCB. The northern extension of the fault along its strike is taken place during Cretaceous and early Eocene, which is also a peak period of depression. After Eocene, the fault zone is mainly in compressional regime with slight right-lateral strike-slip movement.
    Those faults consisting of northeast Asia strike-slip fault system are very complicated and can not be sumarised by a simple model of Mesozoic left-lateral trench fault system, although strike-slip movement dominate their history of evolution. The development and evolution of the strike-slip fault system is closely related to its geodynamic background, i.e. collision between NCB and SCB as well as subduction of Farallon plate, Izanagi plate and Pacific plate under east Asia continent.Late Cenozoic tectonic events seriously deformed or displaced the preexisting Mesozoic structures which must be considered during reconstruction of Mesozoic geology.
