【摘要】特拜金矿位于朱扎拉嘎-甲生盘成矿带上,成矿地质条件优越.结合区内地质工作,对研究区内成矿地质背景 、矿区地质特征 、矿床地质特征等进行了综合分析,厘定了矿床的成因类型,并对研究区内的找矿标志进行了详细地探讨,研究表明:① 该矿床为岩浆后期热液充填交代蚀变岩性金矿;② 研究区内发现的矿体主要赋存于绢云母千枚岩中;③ 矿体主要赋存于大型构造破碎带及其次级断裂交汇处;④ 矿床围岩蚀变具有明显的分带性,近矿蚀变主要以黄铁矿化 、毒砂化 、硅化为主,远矿蚀变主要为绿泥石化 、碳酸盐化 、高岭土化.%Tebai gold deposit is located in Zhuzaraga-Jiashengpan metallogenic belt ,the metallogenic geological condition is superior .Combined with the geological work area ,the area of geological background , geological characteristics ,ore deposit geological characteristics are analyzed .The types of ore deposits are determined ,and the study area of prospecting are discussed in detail .The results show that the deposit is a magmatic hydrothermal filling metasomatic stage change of lithology of gold .The orebody was found in the region mainly occurs in the sericite phyllite .The ore bodies mainly occur in the large tectonic fracture zones and their secondary faults .The deposit rock alteration has obvious zonation ,near ore alteration mainly in pyrite ,arsenopyrite , silicification ,
