摘要
马雄金矿是桂西北典型的微细粒浸染型金矿。通过对该矿床地质特征的重新认识后认为,矿体严格受地层、岩性、构造等控制,矿石类型有硅质矿石、粘土质矿石、黄铁矿质矿石和砷质矿石,元素组合标志以A u-A s为特征,围岩蚀变以黄铁矿化、毒砂化、硅化、褪色化为特征,并总结了该矿床的找矿标志。
Maxiong deposit in northwest Guangxi is a typical ting to fine grain disseminated gold deposit with the orebody strictly controlled by strata, lithology and structure, etc through relearning the geological characteristics of this deposit. Ore types include siliceous ore, clay ore, pyrite ore and arsenic ore with Au- As as the main elements assemblage. The country rock alteration is characterized by pyritization, arsenopyritization, silicification and depigmentation. Finally the indication for ore prospecting is concluded.
