摘要
卡拉麦里构造带为新疆北部一条大型断裂带,带内发育多个规模不等的金矿床与近百个金矿点和金矿化点,为一条重要的区域性金矿带。在综合分析卡拉麦里构造带及邻区地质演化基础上,对其金矿化的形成与定位进行较深入探讨。认为,发育在该矿带的金矿化作用,主要受古生代洋壳消减与后续增生碰撞造山事件所形成的韧性剪切带控制,是典型的造山型金矿系统。由于造山型金矿系统具成矿深度大、构造控制突出、二维延伸稳定等重要特点,预示卡拉麦里金矿带深部具可观的资源潜力。
The Karamaili ductile shear zone is a regional northwest-trending fault belt,and also a huge gold metallogenic belt as well, in the northern Xinjiang.Gold ore-genesis and localization are mainly controlled by ductile shearing induced by the Paleozoic accretionary and/or collisional orogenic events in the region.Thus gold deposits hosted within Karamaili shear zones are typical of orogenic gold systems with the inherent attributes including large mineralized depths,robust structural controls,steadystrike and dipping extensions of ore shoots,which imply that the Karameili gold belt has a great resource potential in depths.
