Abstract: The successfully exploration of Shimensi super-large tungsten deposit, Dahutang area, Wuning coun- ty, Jiangxi Province, is an important discovery of the geological prospecting work in our country. The mineralization type of the deposit is divided into veinlet-disseminated type, cryptoexplosion breccia type and quartz thick vein type. The host rock of the veinlet-disseminated type deposit which accounting for about 14.86 percent of total reserves, are the Late Jinningian biotite granodiorites and the mineralization mother rock are the middle stage of Yanshan solid plutonic-hypabyssal granites. The orebodies are thick with gentle occurrence and appromately parallel to the contact surface of biotite granodiorite and the top of porphyraceous biotite granite stock. In addition, some features of the orebodies are described in this pa- per, such as external contact zone is important contact type( I 1 orebody), horizontal projective surface area is 1.50kmz,maximum thickness of single engineering is 389. 33m, average thickness and grade are re- spectively 143.67m and 0. 193~, change coefficient of thickness and grade are 63.7% and 115.8%, re- spectively. Industrial minerals are scheelite, wolframite, chalcopyrite and molybdenite. Ore textures are mainly crystal structure, metasomatic texture, ore structures are mainly veinlet and disseminated and wall rock alteration are protolithionite, greisenization and chloritization. It is a postmagmatic hydrothermal de- posit with high-middle temperature and is divided into veinlet disseminated scheelite. It is found that bi- otite granodiorite is the host rock of veinlet disseminated scheelite in Shimensi mining area, which change the prospecting thinking of paying more attention to quartz thick vein wolframite and point a new direction for tungsten polymetallic ore-search breakthrough in this area and Jiuling ore concentrating area.
