东川铜矿是一个赋存于浅变质岩系内白云岩岩层中的似层状铜矿.有关单位在为国家探明了大量铜矿资源的同时,对该铜矿的成矿规律、找矿标志等方面都做了不少的研究,积累了丰富的经验.对于矿床的成因,提出了“沉积变质”成矿的看法.1972年,我专题组曾赴矿区学习,并进行了短期野外工作.本文是在学习兄弟单位经验的基础上,根据对含矿岩系岩石特征的研究、硫化物硫同位素分析及电子探针分析等资料,对成矿特点、控矿条件及找矿标志等问题提出的初步看法,并认为该铜矿属于火山-沉积
The Dongchuan copper deposit is a stratiform copper deposit hosted in dolomite strata of the shallow metamorphic rock system.While the relevant units have proved a great deal of copper resources for the country, Mine signs and so on have done a lot of research, has accumulated rich experience .For the genesis of the deposit, proposed “deposit metamorphism ” metallogenic view .In 1972, my group had to go to the mining area to study and carried out Short-term field work.This paper is based on the experience of brothers unit learning, based on the study of rock characteristics of ore-bearing rock series, sulfur and sulfur isotope analysis and electronic probe analysis and other data, the characteristics of the ore-forming, ore-controlling conditions and prospecting Signs and other issues put forward the initial view, and that the copper belongs to volcano - sediment
