| Abstract: | Shanqipan area is located near the NS-trending molybdenum anomaly zone from Qian＇echong in Guangshan County to Shan- gqipan 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 l ： lO000. 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. |
