智利劳斯奎洛斯(Los Quilos)铜矿床赋存于下白垩统Los Chilcas单元钙碱性安山岩及安山质熔结角砾岩中,矿体呈脉状、似脉状、透镜状,形成群脉状分布的多个矿化中心。矿体受走滑剪切的NW向、SN向、NE向断裂控制,断裂及微裂隙的高渗透系统成为热液流体的流动通道和成矿空间。矿物组成主要为斑铜矿、辉铜矿,黄铜矿;以矿体为中心,内带为斑铜矿-辉铜矿-赤铁矿,外侧及向深部为黄铜矿及黄铁矿。区域蚀变普遍,有赤铁矿化、青磐岩化、钠化等;与铜矿化有关的蚀变作用为硅化、碳酸盐化或绿泥石化、赤铁矿化,钠化或钾化。找矿标志为中生界火山-沉积岩系、高渗透构造带、孔雀石化蚀变等特征。
The Los Quilos copper deposit, located in the Los Chilcas unit calc-alkaline andesite and andesite-bearing breccia in the Lower Cretaceous, has a vein-like, vein-like, lenticular-like pattern that forms A cluster of multiple mineralization centers. The high permeable systems controlled by NW, SN, and NE faults controlled by strike-slip shear, fractures and micro-fractures are the flow channels and mineralization space for hydrothermal fluids. The main minerals are bentonite, chalcopyrite and chalcopyrite; the orebody is the center, the inner zone is the bornite-chalcocite-hematite, the chalcopyrite and pyrite are the outer side and the deepest part. The regional alteration is widespread with hematite mineralization, metamorphism, sodiumification and so on. The alteration related to copper mineralization is silicification, carbonation or chloritization, hematite, sodium or potassium The Prospecting signs for the Mesozoic volcano - sedimentary rocks, high permeability zone, peacock petrified alteration and other characteristics.
