The ore bodies in the Shimensi deposit are stratiform, pipelike and veinlike in form and occur in the upper part of the Yanshanian acidic granitic body and also along the external contact zone of the biotite granodiorites of late Jinning period. Wolframite, sheelite, chalcopyrite and molybdenite are the main ore minerals. The ore is mainly in crystallization, replacement and solid separation texture and in vein, dissemination, patch and massive structure. The alterations of the host rock are mainly alkali-feldspathization, greisenization, chloritization and silicification. Genetically, the deposit belongs to the postmagmatic hydrothermal W-Cu-Mo deposit. According to characteristics of the ore body, mineral assemblage, ore fabric, metallogenic zoning and host rock alteration, the main ore bodies can be further divided into veinlet-dissemination type, hydrothermal crypto-explosion breccia type and thick-vein type. These kinds of ore bodies which surround the host rock of Yanshanian acidic granite body form the Shimensi ＂one area-three ore types＂ tungsten-polymetallic deposit. The prospecting for the vein- let-dissemination type scheelite in the Shimensi deposit changes the previous prospecting which focused only onthe thick vein type of wolframite, and provides a new direction for the main breakthrough in the prospecting for tungsten polymetallic ore bodies in the Shimensi deposit and also in the Jiuling ore concentration area.
