摘　　要：以现代成矿理论指导为研究基础,根据大地构造发展阶段及特定的大地构造环境、金矿床在不同成矿体系的成矿时代、地质成矿条件及空间分布规律特点,对广西金矿床按规模大小进行系统地统计和分析,且划分成六个金矿成矿带。通过分析金矿分布的等密线图,得出广西金矿成矿的时空分布总体特征与大地构造单元的依附关系。为今后寻找金矿提供一定的地质理论指导,在新的找矿方法中具有填补性和实用性。Based on modern metallogenic theories,and according to geotectonic process phases and specific geotectonic environment,this paper describes metallogenetic epochs,metallogenic conditions and characteristics of distribution regularities of gold deposit in different metallogenic systems.also analyzes the scales of gold deposits in Guangxi and divides them into six metallogenic belts.After analyzing the distribution isodensity map of gold deposit,the author believes that the general space-time distribution characteristics of gold deposits in Guangxi are dependent on geotectonic units.This paper can be a theoretical guidance and it offers new effective and practical methods in the gold prospecting works in the future.
