Especially in recent years,it has played an important role in Tarim oil exploration and achieved some val ble exploration res lfs. The Mazhatake str ct re is first proposed as a point of view of step fa lt type of anticlinal st ct re zone w ith tw o lines of height w hich are separately in north and in so th by detail gravity s r- vey of Bach area, Tarim Basin. The res lt has been proved by later CEMP and seis- mic prospecting and provided the basis for later oil appraisal of the str ct re zone. : , , Subject ter s gravitational and magnetic prospecti
