本文以深部地质及板块地质为背景,揭示了广西金矿成矿地质特征。根据与地壳厚度为36公里的等厚线大致吻合的桂林—凭祥断裂带,广西可分为东西两大成矿背景区。两区的地质发展历史、成矿演化过程很不相同,形成的金矿床类型随之各异。论述了区内五大类主要金矿床类型,从时控、层控、构控与岩控四方面分析各类型金矿的成矿地质条件,提出广西金矿“长期演化多因复成”的初步认识。在此基础上,划分成矿区和预测区并提出找矿远景。
In this paper, deep geological and plate geology as the background, revealing the geological characteristics of gold deposits in Guangxi. According to the Guilin-Pingxiang fault zone roughly consistent with the isograd thickness of 36 km, the Guangxi can be divided into two major mineralization background areas. Geological development history of the two regions, the evolution of mineralization is very different, the formation of different types of gold deposits. The five major types of gold deposits in the area are discussed. The geological conditions of various types of gold deposits are analyzed from four aspects: time control, layer control, structural control and rock control. understanding. On this basis, divided into the mine area and the prediction area and put forward prospecting prospect.
