内蒙古白音哈尔金矿矿床类型与金的赋存状态

The Occurrence of Gold and the Type of the Baiyinha’er Deposit, Inner Mongolia, China

摘要: 白音哈尔金矿共发现金矿化(脉)体10余条,分别赋存于近南北向、北北东、近东西向三组构造破碎带中.矿化体规模不等,以4、2号脉(群)规模较大,初步认为白音哈尔金矿矿床成因类型为石英脉-蚀变岩金矿,金以自然金的形式赋存于多种矿物中.矿化体严格受断裂构造控制,产于华力西晚期石英闪长岩中,围岩有一定蚀变.

Abstract: There are ten mineralization bodies or ore bodies in the Baiyinha'er gold deposit, which occur along the SN, NND and EW structure fracture zones. The sizes of ore bodies are different, and the size of No.4 and 2 veins are bigger. The type of the Baiyinha'er gold deposit is quart zvein-alteration type, and the gold is found in many kinds of minerals as the natural gold. The ore bodies, which occur in the late Caledonian quart z-diorite, are cont rolled by faults. And wallrock alteration is found in the ore district.
