TECTONIC DEFORMATION CHARACTERISTICS AND ORE-CONTROL SIGNIFICANCE OF THE SANJIASHAN DUCTILE SHEAR ZONE IN BEISHAN OROGENIC BELT, XINJIANG

  • 摘要: 为进一步查明北山造山带北缘三架山韧性剪切带的构造运动学特征及控矿意义,在充分收集前人工作成果的基础上,通过开展系统的野外地质调查工作,基本查明了韧性剪切构造带的空间分布、物质组成、力学性质,在充分分析研究典型构造现象的宏观及显微构造变形特征基础上结合韧性剪切带内卷入地层变质特征和剪切带内岩石组合特征,认为三架山韧性剪切带属中浅部构造相,总体上反应出逆冲—左行走滑的特征。结合带内已发现的产于前寒武系变质基底的铅锌矿和韧性剪切带内的金矿赋矿特征,认为该韧性剪切带对前寒武系变质结晶基底的活化、古生代火山—沉积盖层的改造起到了至关重要的作用,具有明显的导矿、控矿作用。
