本文所讨论的变质岩铜矿主要是指产于沉积变质岩中,成矿地质受沉积作用控制、变质作用改造,并在一定程度上受火山作用影响的矿床.一矿床的主要地质特征1.矿化的空间展布在一个地区,变质岩铜矿的矿化分布受特定的层位控制,并沿一定的方向延展,矿化带可长达数十公里,厚可达数十到数百米(一个地层“组”或“段”).矿化带中的含矿层往往呈多层状产出,单层厚数十厘米到数十米.变质岩铜矿的矿体呈顺层(或沿片理方向)的层状、似层状及沿层断续出现的透镜状产出.浅变质地区,矿体形态简单,变化小;深变质地区,矿体形态较复杂,多分支复合,但主体部分仍保持顺层状态.矿化带
Metamorphosed copper and copper deposits discussed in this paper mainly refer to the deposits that occur in the sedimentary metamorphic rocks, whose metallogenetic geology is controlled by sedimentation, altered by metamorphism and to some extent affected by the volcanism.Main Geological Characteristics of a Deposit Mineralized space spread in an area, the metamorphic rock copper mineralization controlled by a particular horizon, and along a certain direction of extension, the mineralization zone can be up to tens of kilometers, the thickness of up to tens to hundreds (A formation “group ” or “section ”) .Mineralized belt in the ore-bearing layer is often multi-layered output, single layer thickness of tens of centimeters to tens of meters.Metallogenic copper ore body Stratified, stratified and intermittent lenticular output along the strata (or along the direction of stratification). The shallow metamorphic area has a simple ore body with small changes. In the deep metamorphic area, the morphology of the ore body is complex , Multi-branch compound, but the main part remains the bedding state
