1矿床地质概况普朗铜矿床所处的大地构造位置属扬子地台西缘义敦岛弧带南端的格咱岛弧,其东部和南部是甘孜-理塘板块结合带,西部是近NS向展布的乡城-格咱深大断裂。普朗铜矿位于普朗-红山铜多金属成矿亚带,受印支期壳幔型中酸性斑(玢)岩控制,出露地层主要为上三叠统,自上而下可分为曲嘎寺组(T3q)、图姆沟组(T3t)和喇嘛哑组(T3lm)。其中曲嘎组由复理石砂板岩、碳酸盐岩夹中基性火山岩组成;图姆沟组由砂板岩夹中-酸性火山岩构成,分布范围和厚度大于曲嘎寺组;喇嘛垭组下部为海陆交互向碎屑岩,上部为典型的陆相沉积。火山岩主要是以安山岩为主的钙碱系列玄武岩-安山岩组合。
Geological Survey of the Deposit 1. The geotectonic location of the Pulang copper deposit belongs to the grid of the island at the southern end of the Yidun Island arc belt on the western margin of the Yangtze Platform. The eastern and southern parts of the grid are the combination of the Garze-Litang plate and the western part is near NS To the distribution of the township - Georgia deep rupture. The Perlong copper deposit is located in the Prang-Hongshan copper-polymetallic metallogenic belt, controlled by the Indosinian crust-mantle-type acid-plaque (玢) rock. The exposed strata are mainly Upper Triassic and can be divided from top to bottom For the Quqa group (T3q), the Tumen group (T3t) and Lama dumb group (T3lm). Among them, the Qu-Ga Formation consists of dolomitic sand-slate and carbonate sandstone-base volcanic rocks. The Tumugou Formation is composed of sand-slate intermediate-acidic volcanic rocks, and the distribution range and thickness are greater than that of the Quaji Group. The lower part of the sea-land interaction clastic rocks, the upper part of a typical continental deposition. Volcanic rocks are mainly based on the andesite series of basalt - andesite combinations.
