Abstract：Based on analyzing drilling and physical data,the paper realized separation of gravity and magnetic anomalies,picked up and strengthened the data of gravity and magnetic anomalies relative to volcanic rock and synthetically studied the developing feature of Yingcheng Formation volcanic rock in the area by pickup of weak gravity and magnetic data,stripping of gravity anomaly and joint inversion and interpretation of gravity,magnetic and seismic data.The studied results showed that the distribution of Yingcheng Formation volcanic rock is wide in the area,the lithology is mainly the acid volcanic rock that is strip distribution along the main-controlling faults,the lithologic facies is mostly explosion facies,the pattern of magnetic anomaly is mainly circle.
