| Abstract: | The Shiyaogou deposit is a large molybdenum deposit newly discovered in the East Qinling molybdenum belt. In the mineralization area are developed Au, Pb, Mo, Ag anomalies and scheelite, bismutite and native gold heavy mineral anomalies in river sediments. Mo mineralization emplaces at intersection of the EW-trending Machaoying fault and the NE-trending Jiaoyuan fault. Granoporphyry and the host rock-Xionger group with Mo mineralization are all intersected to depth. In plan the Mo mineralization body is elliptical pods with length of 1 050 m, width of 450 m and thickness of 202-1 071 m. The grade is w（Mo）=0. 030%-1.30%, averagely 0.06%. Areal wallrock alteration occurs in zonation. Silicifica- tion and feldsparization are closely related to mineralization. Genetically, the Shiyaogou deposit is porphyry type Mo deposit. Further exploration should be targeted to intersections of EW-trending and NE-trending fault in the area. |
