Jiyang depression is a field where nonhydrocarbon is rich. these resources have close relation with the activities of the volcanos. at the same time, the activities of volcanos have deep contact with the activities of the faults. the growth of the faults in jiyang depression is great. by the research of the index number of the faults growth and the other researches, nw direction faults are the most ones in mesozoic, nw and ne and approximately ew directions all exist in cenozoic. the above reflects the whole geotectonic background that sinistral shearing stress field exists in mesozoic, but dextral shearing stress field exists in cenozoic
