概述云南某铜矿床在构造上位于康滇地轴东侧的次一级隆起中.该矿床从含矿带的分布,矿体产出形态,矿石组份及结构、构造,硫化物的带状性等方面所具有的特点,应属比较典型的沉积-变质矿床.本文试图从找矿、勘探角度探讨矿床的展布特征,并阐述在此基础上进行成矿预测所取得的效果.与本文叙述有关的地层属元古界昆阳群.自下而上为因民组(厚度大于360米)、落雪组(厚140～485米)、黑山组(厚度大于800米),均呈过渡接触,主要为碳酸盐建造.岩浆岩除少量中性火山岩外,一般为蚀变强烈、具钠黝帘石化的辉长-辉绿岩,多呈岩墙、岩床、岩脉及岩瘤产出.部分地区可见辉长岩与震旦系陡山沱组地层呈沉积接触,应属晋宁期.
In summary, a copper deposit in Yunnan Province is structurally located in the eastern uplift of the Kangdi-Dian axis, which is characterized by the distribution of ore-bearing belts, the ore body’s oreform, ore composition and structure, structure, Sex and other aspects of the deposit should belong to the typical sedimentary-metamorphic deposit.This paper attempts to explore the distribution characteristics of ore deposits from the prospecting and exploration perspectives, and expounds the results obtained on the basis of this. The strata associated with the Proterozoic Kunyang Group are described from the bottom up to the Yinmin Formation (thickness greater than 360 m), Snowfall Formation (thickness 140 ~ 485 m) and Montenegro Formation (thickness greater than 800 m) , Mainly carbonate.The magmatic rocks except for a small amount of neutral volcanic rocks, are generally strong alteration, sodium zoisite feldspar - diabase, mostly dikes, bedrock, dikes and lithoma products In some areas, visible gabbro is in contact with the Sinian Doushantuo Formation, which belongs to the Jinning Period.
