Abstract：The developed inverted faults in Liaohe Depression have various form of expression,such as the lower-normal and upper-reverted fault,the reverse fault with inverted fault plane and inverted fault with flower-structural character.The inverted faults of Liaohe Depression are distributed in the east faulted depression,west faulted depression and Damintun faulted depression of second structural unit.Most of them are born in main fault parts having NE and NNE directions that controlled the deposition of faulted depression.Only some of faults were inverted in the same fault system controlling the development of faulted depression and only some segments were inverted in same fault.The characters of coexistence of normal and thrust faults in depression and combination of normal segment and reverse segment in same fault are formed.The inverted faults in Liaohe Depression belongs local inversion,being of benefit to oil/gas accumulation.
