摘要
Soil geochemical and geophysical methods were employed to investigate the comprehensive anomalies in the western part of the Qianjinxiang deposit.The results show that Ⅵ anomaly with the biggest scale,highest intensity and multiple concentration center is caused by concealed granite in the deep part which is intimately associated with mineralization.Three amplitude frequency anomaly districts were delineated at the place of Ⅵ anomaly by using the induced polarization method,which could be employed to infer the burial depth and attitude.In combination with the continuous conductivity measurement by using EH4,the authors inferred the burial depth,the attitude of the ore body and the favorable mineralization location.Drilling test revealed a molybdenum ore body with high grade and large thickness.It is thus suggested that Qianjinxiang is a favorable place in search for porphyry Cu-W-Mo deposits,and soil geochemical survey in combination with induced polarization method and EH4 is a useful means for low-cost and high-efficiency exploration in this area.
