| 摘 要： | 在前人矿床地质和找矿勘探研究基础上，结合较新工程地质揭露认识以及较新分析测试资料，二台子金矿床显示Au-As-Cu-Sb-Mn-Ba的成矿元素与示踪元素组合；矿石中S同位素组成富集重S，不出现塔式效应，具多种混合S的来源特征；H、O同位素组成显示大气降水的强烈参予；矿化蚀变矿物稀土元素配分模式显示出矿床形成对容矿岩石组分的明显继承；矿床地质地球化学特征与美国卡林金矿床存在许多可类比之处。二台子金矿属于具有沉积－改造成因特征的“秦岭式”卡林型金矿床。

| Abstract: | The Ertaizi gold deposit has the same assemblage of ore forming elements and associating tracer element of Au As Cu Sb Mn Ba. The sulfur isotope component in the ores is rich in heavy sulfur isotope and presents no tower style distribution,shows the characteristics of serveral different kinds of sulfur source.The hydrogen oxygen isotope composition shows that meteoric water is strongly involoved in ore forming process.The rare earth elements(REE) mode of distribution in the metallizing altered minerals obviously indicates the inheritting of ore forming elements to the host rocks.On geological and geochemistry characters,this deposit is analogous with the Carlin gold deposit in American.Therefore,the Ertaizi gold deposit belongs to Qinling pattern Carlin type gold deposits featuring sedimentation reform genesis. |
