摘　　要：矿区位于秦祁昆晚加里东造山系,成矿带属大海滩-什多龙印支期Pb、Zn、Sn(Cu)成矿亚带,具有较好的成矿条件。矿区内北西向断裂为主要的控矿构造,并控制了斜长花岗斑岩体的分布,而斑岩体与铜多金属矿体成矿关系密切,其原生晕在垂向上大致为Cu(Au)-Cu+Mo-Mo+Cu-Mo分带;在横向上自斑岩体中心向外大致为Mo-Cu+Mo-Cu-Pb(Pb)+Zn分带,围绕斑岩体在原生晕分带上共圈定铜、钼矿体69条。根据区域矿产分布,以加当根为中心向外围成矿规律显示有高温-中温-低温的趋势,具有巨大的矿产资源潜力。The mining area is located in the late Caledonian orogenic system of Qinqi-Kun,and the metallogenic belt belongs to the Pb,Zn and Sn(Cu)metallogenic sub-belt of the Dashian-Shdorong Indochinese epoch,which has good metallogenic conditions.The NW fault in the mine is the main ore-controlling structure and controls the distribution of plagioelongated granite porphyry,which is closely related to the mineralization of copper polymetallic ore bodies,and its primary halo is roughly Cu(Au)-Cu+Mo-Mo+Cu-Mo zoning in the vertical direction.There are roughly Mo-Cu+Mo-Cu-Pb(Pb)+Zn zonings from the center of the porphyry in the lateral direction,and 69 copper and molybdenum deposits are delineated around the primary halo zonings of the porphyry.According to the regional mineral distribution,the metallogenic regularity of Jiadang root shows the trend from high temperature to middle temperature to low temperature,which has huge mineral resource potential.
