| 摘 要： | 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.

| Abstract: | The petrochemical composition and race-earth ,trace and ore-forming element contents of ore (mineralization) body I and country rocks in TUWU copper deposit are examined in this paper. The distribution and assignment patterns of these elements in ore and country rocks are statistically analyzed with MVSP and GEOKIT systems. According to the similarities between ore and porphyries about element associations in TUWU deposit district, we consider that they have a material relationship .The geochemical actions of ore-forming elements explain that porphyries with initial elements as Cu, Au, Ag, Sb, (Mo) are rich in appropriate spaces of faults and lithofacies after hydrothermal alterations which make the ore forming elements in porphyries active transfer. On this base, ore-forming elements borne with complex-genetic hydrothermal solutions repeatedly piled in later stage , finally formed the large porphyry-hydrothermal copper deposit . |
