我国天然锌铜金属互化物的发现和特征

THE DISCOVERY FEATURES OF THE NATIVE ZINC-COPPER INTERMETALLIC COMPOUNDS IN CHINA

锌、铜金属互化物是罕见的天然合金矿物 ,由锌、铜两种元素组成。由于形成条件、环境不同及矿物中锌、铜元素含量不同 ,形成系列锌、铜金属互化物。经过对我国近二十年来发现的各类型天然锌、铜金属互化物产出的地质特征 ,物理、化学及光学性质进行的系统研究发现 ,目前我国在不同的地质体中出现多种不同类型的锌、铜金属互化物 ,该类矿物主要形成于高温、还原且缺硫的条件下 ,多数与造岩矿物共生 ,而与多数金属硫化物形成条件不同。

Zinc copper intermetallic compounds are the rare native alloy minerals composed of zinc and copper elements.Owing to the differences of the forming conditions,environment and element content of zinc and copper in the mineral, they formed a homogeneous solid solution of the zinc copper intermetallic compounds series.So far only a few of different zinc copper intermetallic compounds have been discoveried in China.This type of minerals was formed in high temperature and reduction without sulphur. The main type minerals were paragenetic with rock forming minerals and their forming conditions were different from most metal sulphides. This article has reviewed the geological feature and natures of the physics,chemistry and optics of the zinc copper intermetallic compounds.
