在分析土屋铜矿床I号矿体中部主要围岩和矿(化)体的硅酸盐、稀土元素、微量元素及成矿元素含量的基础上,借助MVSP等专业软件系统统计对比了上述示踪元素在各类围岩和矿(化)体中的分布分配规律.根据矿区的斑岩体与矿(化)体在多种元素组合特征上的相似性判断,二者有物质上的亲缘关系.而成矿元素表现出的某些地球化学行为则说明初步聚集了成矿元素Cu、Au、Ag、Sb、(Mo)的斑岩体,经热液蚀变使其中的成矿物质活化迁移,并富集在有利的构造和岩相部位,在后期复合成因热液所携矿质的多期次叠加下,形成大型斑岩-热液型铜矿床.
Based on the analysis of the contents of silicate, REE, trace elements and ore-forming elements in the main surrounding rocks and ore bodies in the central I-body of Tuwu copper deposit, with the aid of the professional software system such as MVSP, Trace elements in all kinds of surrounding rock and ore (body) of the distribution of the distribution law.According to the mineralization of porphyry and ore (chemical) body in the combination of a variety of elements to determine the similarities in the characteristics of both material relatives While some of the geochemical behavior of the ore-forming elements indicates that the porphyry of the metallogenic elements Cu, Au, Ag, Sb, (Mo) is initially aggregated and the ore-forming materials are activated by hydrothermal alteration Migration and enrichment in the favorable tectonic and lithofacies regions. With the multi-phase superposition of minerals carried by the complex hydrothermal fluids in the later period, large-scale porphyry-hydrothermal copper deposits are formed.
