摘　　要：阿沙勒金矿产于上奥陶统呼独克达坂组的一套浅海相火山碎屑沉积岩和碳酸盐建造中,是一个与花岗闪长岩体侵入有关的小型金矿床,矿体产出受控于地层、构造、岩浆岩。从矿床地质、流体包裹体、稳定同位素等角度较详细论述了金矿的地质特征,并进一步探讨了矿床成因,认为其属华力西早期的岩浆热液型金矿床。The Ashale gold deposit is a small one which is confined to neritic pyroclastic sedimentary rock and carbonate rock of the Upper Ordovician Hudukedaban Formation and is related to granodiorite. Gold orebodies are con-trolled by strata, structures and magmatic rock. Ore genesis is discussed in terms of geological features, fluid inclusions and stable isotope. The gold deposit is a magmatic hydrothermal one which was formed in the Hercynian epoch.
