摘要:
长安金矿床位于哀牢山断裂南段，同时受甘河断裂与藤条河断裂、三家断裂与甘河断裂挟持。矿区内矿体受地层及岩性、构造、岩浆岩控制。F6断裂是矿区目前发现最重要的控矿构造，沿F6断裂及其上盘附近共发育3组不同产状矿体，分别为产于F6断裂破碎带中矿体、产于F6断裂上盘附近向东陡倾斜矿体、产于F6断裂上盘向东缓倾斜矿体；3组矿体均具有尖灭再现、雁列式排列特征，在空间上具有较大找矿潜力。北西向、北北西向、近南北向断裂与成矿关系密切，同样具有较大找矿潜力；岩浆岩与成矿关系密切，深部及外围具有寻找矽卡岩型矿体的潜力。

Abstract:
Chang’an Gold Deposit is located in the south part of Ailaoshan fault,simultaneously controlled by Ganhe fault and Tengtiaohe fault,Sanjia fault and Ganhe fault.The orebodies in the district are controlled by strata,lithology,tectonics and magmatics.F6 fault is the most important ore-controlling structure discovered.3 groups of orebodies with different occurrences develop along the F6 fault and its upper wall peripherals,including the orebodies in F6 fault fractured zone,the steeply inclined orebodies east to the upper wall peripherals of F6 fault,and the moderately inclined orebodies east to the upper wall of F6 fault;the 3 groups of orebodies all are characterized by pinching out and reappearance and echelon layouts,and have great prospecting potentials in space.NW,NNW,near SN faults are closely related to ore forming,and also have great prospecting potentials;magmatic rocks are closely related to prospecting,and there are prospecting potentials for skarn type orebodies in the deep parts of peripherals.
