甘肃省徽县向阳山西铅锌矿田秦岭型铅锌矿床宏观上具有明显的沉积矿床特征,微观上具有热液矿床特征,因此矿床应属沉积受变质的层控型铅锌矿. 通过控矿因素的分析,沉积(成岩)作用是成矿的主要因素,后期变质作用对矿体进行改造,矿体明显受地层层位、岩石组合联合控制. 17、18号矿体深部向北东侧伏部位是成矿有利地段,有扩大远景的可能.
甘肅省徽縣嚮暘山西鉛鋅礦田秦嶺型鉛鋅礦床宏觀上具有明顯的沉積礦床特徵,微觀上具有熱液礦床特徵,因此礦床應屬沉積受變質的層控型鉛鋅礦. 通過控礦因素的分析,沉積(成巖)作用是成礦的主要因素,後期變質作用對礦體進行改造,礦體明顯受地層層位、巖石組閤聯閤控製. 17、18號礦體深部嚮北東側伏部位是成礦有利地段,有擴大遠景的可能.

The Western Xiangyangshan lead-zinc ore field with Qinling type in Huixian, Gansu province, macroscopically features obvious sedimentary deposit, and microscopically presents hydrothermal deposit.So the deposit should belong to sedimentary metamorphic type stratabound lead-zinc mine.Through the analysis of ore-controlling factors, sedimentary effect is the main factor of mineralization and altered by the late metamorphism of ore bodies, the ore body is clearly jointly con-trolled by the stratigraphic and rock combination. The deep of the17# , 18# ore body in northeast trend lateral position is the favorite prospecting area, has the potential to expand the vision.to the north east of v parts is the favorable area for,
