FEATURES OF THE JIYANG MOVEMENT AND ITS EFFECTS ON THE EVOLUTION OF THE JIYANG DEPRESSION

Three important characteristics of the Jiyang movement at the end of No. 4 Sha section of the Jiyang Depression are as follows:both regional tectonic movement and the ups and downs of block faulting as well as the episodic tiltings of faulted blocks. The origin of the Jiyang movement is closely related to the transformation of the Tanlu Fault Belt from sinistral to dextral movements. Therefore, it is a significant tectonism for the development of the Jiyang Depression, and could play an important role on the generation,migration and accumulation of oil/gas in the depression and also provide regional settings for oil formation.
