摘要
通化地区早元古宙集安群变质岩系中,分布着众多的铁帽,其含金量各异。本文在地质、物探资料综合解释的基础上,分析了控矿铁帽产出的地质条件,对铁帽中的金等元素组合做了统计分析,以数量化理论划分了三种铁帽类型,其中含钒、钛的铁帽,系铁质岩石氧化而成,为假铁帽与金矿无关;铅、锌硫化物的铁帽也与金矿无关;而含铜硫化物铁帽则含金较高,具有指示找金的意义。
In accordance with thecomprehensive geological information theory. A comprehensive appraisal on different gossans of Jian group is presented by using the quantitation method Ⅲ in this paper, which based on chemical analysis data and the gossan control conditions derived from geological and geophysical exploration.We focus on the forecasting of auriferous gossans and reveal the target locations for further exploration of auriferous ore deposit in the district
