在本刊1959年第12期上登載了“云南某地基性岩岩石学上的一些問題”一文,本文将继續扼要地論述此种与基性岩有关的硫化銅鎳矿床。一、地质概述硫化銅鎳矿床与該区的第二期基性岩侵入体有密切关系。到目前为止所发现的硫化銅鎳矿矿化現象有三种类型:(Ⅰ)浸染状;(Ⅱ)純硫化物脉;(Ⅲ)綠泥石硫化物脉。按矿化规模及工业价值而言,第一、二类型較重要。 1.浸染状硫化矿的矿化現象前文已述及該区第二期基性岩体分异良好,自岩体的底部至上部可分为四个岩相带:(1)輝綠岩,(2)橄欖苏长輝长岩,(3)苏长輝长岩,(4)閃长岩。浸染
In the journal issue No. 12 of 1959, there is a paper entitled “Some Problems of Basic Petrophysiology in Yunnan Province.” This article will continue with an overview of such sulfide-nickel-copper deposits related to basic rocks. First, the geological overview Cu sulfide nickel-nickel deposit and the second stage of basic rock intrusions are closely related. There are three types of mineralization of copper sulphide nickel ore so far found: (I) disseminated; (II) Pure Sulphide Veins; (III) Chlorite sulphide veins. According to the scale of mineralization and industrial value, the first and second types are more important. 1. Mineralization of disseminated sulphide ore As mentioned above, the second basic rock mass of the area has well differentiated and can be divided into four lithofacies zones from the bottom to the top of the rock mass: (1) diabase, (2) Olive long gabbro, (3) Su Chang feldspar, (4) diorite.
