吉林省临江市大松树金矿地质特征及找矿标志

The geological features of the Dasongshu Au deposit of Linjiang City, Jilin Province and its criteria for ore prospecting

详细地描述了矿床的地质特征、金矿物特征及赋存状态。根据矿物共生组合划分出成矿期及成矿阶段,分析了控矿的各种因素,确定了找矿的各种标志及采取的手段,特别是采用土壤汞气测量和激电方法能确定深部矿体,为今后在该地区寻找此类型金矿床提供了方法,指明了方向。

In this paper,we made a detailed description o n the geological features of Au deposit,characteristics of the Au minerals and occ urrence conditionAccording to the paragenetic mineral association,the minerali zation epochs and mineralization stages are classified,analyzing the ore-control factors,determining the criteria and the methods for ore prospectingThe metho ds of soil mercury-vapor survey and induced polarization can determine the deep orebodyThese mentioned above indicate the prospecting direction for this kind of Au deposit
