摘要/Abstract

摘要：

富水金矿产于奥陶系不纯碳酸盐岩中，矿化受背斜层间破碎带和E—W向、NW向断裂的复合控制，破碎带均受不同程度硅化，热液蚀变作用明显。金为微细粒浸染型金，肉眼甚至一般光学显微镜中均不可见。笔者根据富水金矿与国内外主要卡林型金矿的异同点、金的赋存状态、矿床同位素、地质特征等对富水金矿床成因进行了探讨。

Abstract:

Fushui gold deposit is hosted in the Ordovician impure carbonate rocks with its mineralization jointly controlled by EW striking and NW striking faults. The fracture zone has undergone silicification and hydrothermal alteration. Disseminated gold are invisible by naked eyes or under optical microscope. This paper, based on a comparison between Fushui gold deposit and major ones alien, discusses the genesis from gold occurrence, isotope and geological features.
