摘要
近年国外铜矿床勘查与研究工作,在成矿理论和勘查方面取得了新的进展.本文介绍了智利埃斯康迪达斑岩铜矿床和圣烛节层控铜矿床,印度马兰杰坎德铜矿床,菲律宾勤班陀富金铜矿床,印尼埃茨伯格矽卡岩铜矿床和格拉斯伯格斑岩金铜矿床,加拿大米利根山和卢维库特铜矿床的勘查工作进展;同时介绍了铜矿床成矿理论和找矿研究工作的新进展,斑岩铜矿床成矿与陆内活化带构造环境有关,成矿作用具多期多阶段特征;层控铜矿床成矿与大陆裂谷环境有关,不同类型矿床与裂谷演变的不同阶段有关,以及层控铜矿床分类的特点.最后,为解决我国铜矿资源,结合我国铜矿床勘查利用情况,提出改进提取技术,开发利用低品位铜矿石的认识和建议.
Serveral recent important copper (gold) ores discoveries in foreign counties,the trends of copper exploration,some understanding of metallogenic theory and prospecting research on porphyry and strata bound copper deposits.and the improvement of exstraction technique for exploitation of low grade copper deposit in foreign countries are described here and also some suggestions which should be taken into account while dealing with resource problems of copper deposits in our country are made in this paper.
