前言四川某铂镍矿是一具有相当大储量的低品位矿床,有良好的开采与建厂条件。矿床内所有含矿超基性岩体的产出都受背斜构造控制,侵入于石炭系大雪组地层中。矿体按超基性岩体与含铂硫化铜镍矿体的赋存关系,分为三种类型:(1)超基性岩型;(2)块状富矿体型;(3)硅质自云岩和矽卡岩型。
Preface A nickel-nickel deposit in Sichuan is a low-grade ore deposit with a considerable reserve and good mining and construction conditions. The output of all ore-bearing ultramafic rocks in the deposit is controlled by the anticlinal structure and intrudes into the Carboniferous Snowfall formation. The ore body is divided into three types according to the occurrence of ultramafic rock mass and platinum-bearing copper-copper-nickel ore body: (1) ultrabasic rock type; (2) massive ore body type; (3) Dolomite and skarn type.
