桂西北地区是右江盆地的主要部分,它位于华南加里东地槽和扬子准地台的过渡带,该区位于特提斯洋构造域东端与太平洋构造域交汇的部位,应力集中,构造变形强烈,是全球地幔对流环的两个会聚中心之一。区内基性岩浆活动频繁,是成矿条件很有利的地区,曾经发生了大规模的成矿事件(刘希军等,2013)。该区地属于我国著名的滇黔桂“金三角”地区,也是广西最重要的微细浸染型金矿分布区,而马雄金矿是桂西北典型的微细粒浸染型金矿。通过对该矿床地质特征的认识,简单探讨马雄
The northwestern Guangxi is a major part of the Youjiang Basin. It is located in the transitional zone between the Garton Trough and the Yangtze Platform in South China. This area is located at the intersection of the eastern tip of the Tethyan Ocean and the Pacific tectonic domain, with stress concentration and tectonics Deformation is strong, is one of the two convergence centers of global mantle convection loop. In the area, the basic magmatic activity is frequent, and it is a very favorable metallogenic condition. Large-scale metallogenic events have taken place (Liu et al., 2013). The area belongs to China’s famous Yunnan, Guizhou and Guangxi “Golden Triangle ” area, Guangxi is also the most important fine disseminated gold distribution area, while Ma Xiong gold mine is a typical micro-disseminated gold mine in northwestern Guangxi. Through the understanding of the geological features of this deposit, Ma Xiong is briefly discussed
