硫化铜镍矿床一般多赋存在基性-超基性岩体内的特定岩相里,硫化铜镍矿体在基性-超基性岩体中,具有一定的空间形态和一定的地质位置,硫化铜镍矿床和基性-超基性岩体在成因上和空间上,存在有一定的依附关系.事实已经证明,在基性-超基性岩体中并不是全部都含有工业矿体的,只是在部份基性-超基性岩体中含矿.已知含矿岩体,有超基性岩在边部基性岩在中心的,辉长岩一二辉岩—橄榄岩-橄榄辉岩型岩体和基性岩在边部,超基性岩在中心的橄榄岩一二辉橄榄岩-纯橄榄岩型岩体…等等.本文仅就个人对在基性-超基性岩有关的硫化铜镍矿区,进行普查和勘探时应注意的几个问题,从现象方面提出一些粗浅的看法,供普查和勘探硫化铜镍矿床的地质工作者参考.
Copper sulphide-nickel ore deposits are generally distributed in specific lithofacies within the basic-ultramafic rocks. The copper-nickel sulphide ore bodies have certain spatial patterns and certain geological locations in the basic-ultramafic rocks, Copper sulfide-nickel-copper deposits and basic-ultramafic rocks have some dependencies on their genesis and space, and it has been proved that not all of the basic-ultrabasic rocks contain industrial ore bodies , Only in part of the basic - ultramafic rocks contain ore known ore-bearing rocks, there are ultrabasic rocks in the marginal basic rocks in the center of gabbro periclase-peridotite - Oligochlora-type rock mass and mafic rocks at the margins, ultramafic rocks in the center of the peridot ophiolite-dunite rock type ... etc .. This article only on the basis of individuals - super-base Several related problems should be paid attention to when surveying and exploring copper sulphide nickel ore areas related to sex rocks. Some superficial views are provided from the aspects of phenomena for reference of geologists who census and prospect copper sulphide - nickel deposits.
