印度尼西亚西爪哇内阁拉萨金矿GA矿区黄铁矿形态标型特征及成矿预测

摘要

黄铁矿是金矿物中最常见的金属矿物,它不仅与金的矿化有着密切的关系,而且还是主要的载金矿物.对内阁拉萨金矿GA区黄铁矿进行晶体形态标型特征的研究.研究发现:本区黄铁矿晶形较简单,主要是{100}、{210}、{111},及它们的聚形体和不规则体.通过研究该区黄铁矿的形态与矿化强度的关系,对该区黄铁矿标型与金矿化预测做了一定的总结.%Pyrite is the most common metal mineral in gold deposit. It not only has a close relationship with the gold mineralization, but also is the main gold-carrier. The crystal form typomorphism of pyrite at GA area in Negla-sari gold deposit is mainly analysed. From the study, it is found the crystal form of pyrite in this area are relatively simple, it shows nearly the crystal of { 100} 、 {210} 、 { 111 } and their combination and irregular shape. Based on the relationship between the morphology of pyrite and the mineralization intensity, a summary of the typomorphic feature of pyrite and the gold mineralization is presented.
