截止一九七八年,国外已探明的镍金属储量为1.13亿吨,其中20％来自与基性、超基性岩有关的铜镍硫化物矿床。较为著明的有加拿大的肖德贝里、苏联的诺里尔和贝辰加、澳大利亚的佩瑟湾兰斯等。解放以后,在甘肃、四川、吉林,青海和新疆等地先后查明并开发利用了一批铜镍矿床。及时地总结这些矿床的特征及成矿规律,可以更好地指导找矿勘探工作。本文是在综合研究了国内外铜镍硫化物矿床实际资料的基础上,着重阐明与该类矿床有关的基性、超基性岩的主要特征。
As of 1987, a total of 113 million tons of nickel metal has been proven abroad, of which 20% comes from copper-nickel sulfide deposits related to basic and ultrabasic rocks. Some of the more obvious are Schottberg in Canada, Norriel and Bechenchal in the Soviet Union, Pace Bay Lance in Australia, and so on. After the liberation, in Gansu, Sichuan, Jilin, Qinghai and Xinjiang and other places have identified and developed a number of copper and nickel deposits. Timely summarize the characteristics of these deposits and metallogenic rules, can better guide the prospecting work. Based on a comprehensive study of the actual data of copper-nickel sulfide deposits at home and abroad, the paper focuses on the main features of the basic and ultrabasic rocks related to this type of deposit.
