新疆西天山金矿成矿条件分析及找矿远景

新疆西天山地区是我国重要的矿产资源基地,金矿及有色金属矿矿产资源丰富,该区分布众多的金矿点,同时分布特点具有成带性,寻找金矿潜力巨大。文中详细分析探讨西天山地区金矿成矿条件,通过研究发现,库姆托尔金矿与穆龙套金矿等均和西天山地区处在同一条构造带上,在大地构造环境上非常的类似,同时在构造演化以及赋金建造条件上非常相同。该区金矿主要受控于那拉提构造带南缘的弧形构造带以及对那拉提构造带进行横贯的横向断裂。该区广泛的发育赋金层炭质岩系以及蚀变体,利于活化金元素,促进其富集成矿。该区存在的大量的金矿化及异常,更进一步证明金矿体的存在。据此,笔者预测出4处找矿有利地段。

Analysis of metallogenic conditions and prospecting prospect of gold deposits in Western Tianshan,Xinjiang

The Western Tianshan area of Xinjiang is an important mineral resource base in China.It is rich in gold and non-ferrous mineral resources.There are many gold spots in this area,and the distribution characteristics are zonal,so there is great potential for gold exploration.In this paper,the metallogenic conditions of gold deposits in the Western Tianshan area are analyzed and discussed in detail.It is found that kumtol gold deposit and mulongtao gold deposit are located in the same structural belt with the Western Tianshan area,and they are very similar in geotectonic environment,as well as in structural evolution and gold bearing construction.The gold deposits in this area are mainly controlled by the arc structural belt in the south margin of Nalati structural belt and the transverse fracture of Nalati structural belt.The extensive development of gold bearing carbonaceous rock series and alteration in this area is conducive to the activation of gold elements and their enrichment and mineralization.There are a lot of gold mineralization and anomalies in this area,which further proves the existence of gold ore bodies.According to this,the author predicts four favorable areas for prospecting.
