摘要: 新疆西北部阿尔泰地区发育一套片岩、片麻岩, 从境内铁列克以东的塔乌乃萨孜一带向东南延伸到蒙古阿尔泰山南坡, 统称冲乎尔-青河构造建造带。该带以特殊的构造位置和复杂的变形变质特征, 成为研究阿尔泰造山带发展、演化的重要热点之一。通过对新疆西北部富蕴县苏普特地区前寒武纪克木齐岩群的物质组成、变质、变形方面的资料收集和分析研究, 认为该套地层经受过中深层次的区域动力热流变质作用, 变质达角闪岩相, 是阿尔泰地区前寒武系基底的组成部分, 其变形具有多期次和多层次的特征, 不同构造层次的变形均保留下丰富的构造变形形迹。通过原岩恢复, 认为克木齐岩群总体为一套碎屑(夹火山)-碳酸盐岩沉积建造。Abstract: A set of schist and gneiss developed in Altay, northwestern Xinjiang, extending from Tawunaisazi to the southern slope of the Mongolian Altay, called Chonghuer-Qinghe structural construction zone. Because of special geographical location and tectonic deformation, this zone has become a hot research focus of development and evolution of Altai orogen. By collecting and analysis of the data of the material composition, metamorphism, deformation of the metamorphic rocks(Precambrian) in Altay region, we hold that the strata have undergone in-depth regional dynamo-thermal metamorphism of amphibolite facies, and the strata are part of the Precambrian basement in Altay region. The deformation of the Kemuqi group is multi-stage and multi-level, and reserved extensive tectonic deformation information in different structural levels. By restoring the original rock, the Kemuqi group is a set of clastic rock(volcanic clip)and carbonate sedimentary rocks.
