新疆多拉纳萨依金矿区构造特征与成矿关系
Interrelationship of Shear Structure and Mineralizaion of Duolanasayi Gold Deposit in Xinjiang

摘要: 多拉纳萨依金矿发现于20世纪80年代末,近年研究确认该矿与韧性剪切带关系密切,但对于韧性剪切带如何控制金矿床的形成并未进行深入研究。笔者从地质背景、矿床地质,以及控矿构造分析了多拉纳萨依金矿矿床特征及其成矿机理;明确了矿床产于泥盆系托克萨雷组第三岩性段的灰岩-浅变质-硅质岩系,受控于多拉纳萨依韧性剪切带;控矿构造具有二次韧性剪切变形、矿化和多期次脉体矿化的特征,显示出构造活动的多期次性与复杂性,阐明了构造期次与矿化之间的关系。Abstract: Recent study has related the mineralizaion of Duolanasayi gold deposit (discovered in middle 1980's) to shear structures.However,how the shear structures control the gold mineralizaion is not clear.Based on the geological backg round,ore-deposit and structural geology,the paper analyzed the geological characteristics and metallogenic mechanism of the gold deposit and suggests that the deposit occurring in the limest one and metamorphic siliceous rocks in the third lithologic unit of Devonian Tuokesalei formation is controlled by the Duolanasayi shear zone characteristic of secondary shear deformation,mineralizaion and multiphased vein mineralization.These obviously show multiphase and complexity of the structural activities.
