天井山金矿位于江南古陆东南缘,扬子准地台与华南褶皱系的结合部位。晋宁运动运动结束了华夏古陆向江南古陆俯冲、碰撞和拼贴的过程导致了扬子板块呈准稳定态,并开始了盖层沉积的新阶段(邢凤鸣等,1992)。晋宁期后皖南及其东南侧的华南地区属于边缘海域,具有沟、弧、盆体系和小型地块的复杂大陆边缘特征(王自强等,1990)。该区域经历了多期次构造、岩浆岩和成矿活动,是我国重要的有色及贵金属成矿带。天井山金矿是皖南地区第一个独立的原生金矿床,是该地区规模较大的金矿床,其矿化类型有石英脉
The Tianjing Mountain Gold Mine is located in the southeastern margin of the ancient southern Jiangnan, the junction of the Yangtze Platform and the South China fold system. The movement of Jinning ended the subduction of the ancient Chinese continent toward the southern Yangtze River. The process of collision and collage led to the quasi-steady state of the Yangtze plate and started a new phase of sedimentary cover (Xing Fengming et al., 1992). After the Jinning period, Southern China and southern part of South China belong to the marginal sea area, and have the characteristics of complex continental margins of dikes, arcs, basin systems and small plots (Wang et al., 1990). The region has undergone multiple phases of tectonism, magmatic rocks and metallogenic activities and is an important colored and precious metal metallogenic belt in China. The Tianjingshan gold deposit is the first independent gold deposit in Southern Anhui Province and is the gold deposit of the larger scale in the area. Its mineralization type is quartz vein
