The deep part of Anda fault depression incluses Shahezi formation , Yingcheng formation and Denglouku formation. The three formations are formed in the stage of fault and fault depression transformtion. They are consisted of a series of terrestrial sedimentary rocks with volcanic rocks. According to the rule of sequence stratigraphy, the three formations can be divided into fault depression super sequence. fault depression transform super sequence. The sequence Ⅰ is developed in fault depression super sequence and the sequence Ⅱ and sequence Ⅲ and developed in the fault depression transform super sequence. There are two kinds of hydrocarbon source rock in this region: one is the deep lacustrine dark mudstone on the top of the sequence Ⅲ and another is swamp deposits in Yingcheng formation.
