Sesmic wave field feature in Lisui basin volcanic terrain and location forecasting of ore-controlling factors

Lishui basin of Jiangsu activated to be a diwa in the latter stage of Mesozoic era,and was formated as a volcanic basin under control of magmatism in Yanshan period.The forming of mineral deposit is strictly controlled by volcanic cycles and tectonic.Seismic exploration data reveals that seismic wave field feature of different geological bodies has its salient features.Basin tectonic and interface of volcanic cycles are distinct and the thickness of volcanic series is about 3700meters.The faults in fore-volcanic-sedimentary formation are development,sub-volcanic rocks distribute in the uplift of basin margin.According to the view of metallotectonics,combined to the metallogenic background of the survey area,related deposit types in this region and anomaly of MT section,related ore-controlling factors were prospected.
