摘要
本文从目前金矿在时间、空间上的分布特征、赋金层位和岩性、金矿类型等方面概述了金矿地质现状,在广西50多个县内已发现金矿床、矿(化)点三百余处。在已探明的储量中,有57％左右的金矿产在寒武系中;三叠系的各类型金在预测储量中占45％左右。多期次的构造、岩浆活动形成了种类繁多的金矿床。依据成矿物质来源、成矿作用和矿化特征将广西金矿分成二个大类,七种成因类型九个亚类。本文还对各类型金矿特征作了简介,叙述了各类型金矿找矿的新进展并划分了成矿远景区。
This paper outlines the gold geology of Guangxi from the point of view of time, space, gold-containing stratigraphic positions, lithology, and genetic types. So far more than three hundred gold deposits, mineral occurences and mineralized occurences have been discovered in over fifty counties in Guangxi. 57% of the total demonstrated reserves of gold is associated with the Cambrian. And the gold reserves associated with the Triassic make up about 45% of the total predicted gold reserves. Varieties of gold deposits in Guangxi are the products of numorous tectonic movements and magmatic activities. Based on ore-forming matter sources,metallogeny,and the characteristics of gold mineralization, gold deposits in Guangxi can be divided into two major types, including seven genetic types and nine subtypes. This paper also gives a brief account of the characteristics of various types of gold deposits and the recent developments of gold exploration.
