Wuxia area was located on the eastern of northwest Junggar basin, it was a zone of bruchfalten affected by multiphase tectonic activity, have many faults and its fold morphology were very complicated, underwent three large structural activities, which happened in the late Hercynian movement, Indo-Chinese movement, and the Yanshan movement, by this,strata of Wuxia area can be divided into two primary tectonic sequences and seven secondary tectonic sequences, on plane, Wuxia area can be divided into three secondary structural units from north to south,they are foreland thrust belt, Wuxia fault fold belt and monocline belt, further, from west to east Wuxia fault fold belt can be divided into four fault fold belts.
