四川丹巴燕子沟金矿位于松潘—甘孜造山带,丹巴滑脱-逆冲深层叠置构造岩片内。其矿区区域上的黑色岩系、基性岩脉、永西沟穹窿与两河口、牦牛沟区域深大断裂的发育,均表明丹巴燕子沟金矿控矿构造的复杂性与特殊性。矿区地处永西沟穹窿北西缘,西邻两河口断裂,经历了双向的构造挤
The Yanbaogou gold deposit in Danba, Sichuan is located within the Songpan-Garzê orogenic belt and the Danba slippage-thrusting deep-stacked structural sheet. The development of the black rock series, the basic dykes, the Yongxi ditch dome and the Lianghekou and Yakougou deep faults in the mining area all indicate the complexity and particularity of the ore-controlling structure of the Yanbaogou gold deposit in Danba. The mining area is located in the northwestern margin of Yongxiu ditch dome and the fault of Lianghekou in the west has experienced two-way tectonic squeezing
