Abstract: The Fuquanshan area of Dexing county,Jiangxi province is located in the northern section of Dongxiang-Dexing polymetallic metallogenic belt，a small tungsten deposit and more than ten mineralization point (belt) of Au,Cu,Pb are found in the metallogenic belt.The tungsten resource of the Fuquanshan area is reached to 30 000 t,the tungsten deposit of the area is composed of three sections,which mineralization category is far skarn-type.In order to provide some new theoretical basis for the deep prospecting and exploration and metallogenic study,combing with the results of field geological survey,geophysical and geochemical prospecting survey and drilling reveal of the Fuquanshan area,the regional metallogenic geological background,metallogenic geological characteristics and mineralization characteristics are analyzed in detail,the following conclusions are concluded:①the main metallogenic elements in the Fuquanshan area can be provided by the metamorphic rocks of the Shuangqiaoshan formation,the comprehensive anomalies of geophysical and geochemical prospecting can be taken as indirect prospecting indicators,the green alteration belt can be taken as the direct prospecting indicator;②the concealed granite rock mass is existed in the deep of Fuquanshan area,the rock mass is plunging to the south,the tungsten polymetallic mineralization is closely related to the rock intrusion activities of early Yanshannian.Based on the above analysis results,the metallogenic regularities of Zhuxi tungsten copper of the area is discussed in depth,besides that,the prospecting prediction of the area is also conducted,the results show that the contact zone of deep rocks and limestones is the favourable area for metallogenic,it also the key parts of the further prospecting work in the area,the deposits that are similar to the Zhuxi skarn-type tungsten copper deposits.
