 In this paper, the features of gravity, magnetic and magnetotelluric anomaly in the Coqên basin are described.Based on the geophysical measurements results, geology and petrophysical characteristics in the Coqên basin, the high resistivity zone in the northern Coqên County that locates the zone of rift or graben has been studied synthetically, and it is interpreted as the cause of the paleozoic marine carbonate rocks. The Coqên Basin received very thick deposits during Paleozoic, which indicates that there is potential area for Paleozoic oil-gas prospect.
