摘要
The Xiaoqinling metallogenic belt is a very famous ore concentration area for noble metals in China. The Dongchuang gold deposit is a typical large-sized quartz vein type gold deposit in the Xiaoqinling area which was one important part of the Qinling collisional orogenic belt. It formed mainly in the Yanshannian and its mineralization and evolution was controlled by the mechanisms of the Qinling orogenic movement,especially by faulting. Based on the studies of the geology,structural characteristics,metallogenic periods or stages and mineralization tendency of vein No. 507 of the Dongchuang gold deposit,the authors established the temporal and spatial evolutional relationship between ore field tectonic activities and ore-forming processes,then summarized the mechanisms of structural ore-control. The results will be very useful for the deep prospecting of this crisis mine.
