Characteristics and evolution of Hengshui transfer fault zones in Jizhong depression

In Jizhong depression, Hengshui fault zone is of characteristics of transfer zones, which divided the depression into two north and south regions. By the research on the structure settings of the situated region, the characteristics and its evolution of the fault, it is concluded that the transfer zone gets though two different evolution periods, that is, Mesozoic period (near East-West) and Cenozoic period (North-West-West). The Cenozoic period can be divided into three evolution steps (Es₄ +Ek, Es₂+Es₃, Es₁+Ed), based on their characteristics of deposition and structural development. Modern structure appearance is formed by the superimposed function, reformation, restriction and accommodation of two evolution periods.
