Shanqipan area is located near the NS-trending molybdenum anomaly zone from Qian'echong in Guangshan County to Shangqipan in Xinxian County. The region has good molybdenum ore prospecting potential. The authors made a comprehensive analysis of the combined features of stream sediment geochemical survey at the scales of 1:200000 and 1:50000, with emphasis placed on the soil geochemical survey at the scale of 1:10000. An evaluation was also made on the soil geochemical element association by index of geoaccumulation. Trenching and drilling verification led to the discovery of 7 molybdenum orebodies, thus achieving satisfactory ore-prospecting results.
