新疆青河顿巴斯套金矿地质特征及控矿因素浅析

Analysis on the Geological Feature and Ore-controlling Factors of Dunbasitao Gold Deposit in Qinhe County, Xinjiang

顿巴斯套金矿床位于萨吾尔-二台晚古生代岛弧带，具矿源层、岩脉和构造“三位一体”的成矿模式，构造提供了控矿通道和空间，中．酸性斑岩脉带来大量热源和热液，使矿源层中分散的Au随着热液活动而活化、迁移。经多期热液活动后，形成中一低温破碎蚀变岩型金矿。

Dunbasitao gold deposit is located in Sawuer-ertai Neopaleozoic island arc belt,with the trinity metallogenic pattern of source bed,dyke and structure,the structure provides the ore-controlling channel and space,acidic porphyry vein bring lots of the heat source and hydrothermal,which made the dispersive Au in the source bed activate and migrate with hydrothermal activity, and form the gold mine after much stages ofhydrothermal activity.
