摘　　要：通过分析四川省会理县尖子硐钨多金属矿区域地质背景、勘查区的地质特征、控矿因素,总结勘查区的成矿地质背景和找矿规律,以指导在会理益门——岔河一带发现更多新的钨多金属矿床。目前的勘查成果显示,区内白钨矿具有中-大型规模,其严格受矿区近东西向的F_(3)断层和中元古代凤山营组的矽卡岩控制,同时受中元古代酸性岩浆岩所控制,矿床成因属于矽卡岩型矿床。Based on the analysis of regional geological background,geological characteristics and ore-controlling factors of Jianzidong tungsten polymetallic deposit in Huili County,Sichuan Province,the metallogenic geological background and prospecting regularity of the exploration area are summarized,in order to guide the discovery of more new tungsten polymetallic deposits in Huili Yimen-Chahe area.The present exploration results show that the scheelite ore in the area has a medium to large scale.The deposit is strictly controlled by the near east-west F_(3) fault of the mining area and the skarn of the Middle Proterozoic Fengshanying Formation,as well as the acidic magma of the Middle Proterozoic.The deposit belongs to skarn type.
