| 摘 要： | 出露于库鲁克塔格赛马山一带被前人划分为达格拉格布拉克群的古老变质岩系，通过野外填图及室内分析工作，确定为一套块状无序花岗质正片麻岩，并建立构造岩石单位钎断山片麻杂岩。本文从产状、成分、所含包体、残留的变余结构及侵入关系等地此进行了论证。讨论分析了其岩石类型、变质变形特征和形成时代。该花岗质片麻岩的确认对重新认识库鲁克塔格一带的古老变质岩系和探讨早期地壳演化具有重要意义。

| Abstract: | The old metamorphic rock system outcroped in Saimashan region of Kuruktag. Which was divided into the Dagelabulak Group by early geologists is now identified a set of massive disorder granitic gneiss,based on the field work and the analysis. A Petrological unit of Duduanshan gneiss complex is also set up, this paper puts forward some evidences of actitute, composition, inclosures, the residual brasto structure as well as the intrusion relations. It discussed the rock type, metamorphism and deformation characteristics as well as its forhang time. The ideallcahon of the granitic gneiss has a great signilicance to study the old metamoIPhic rock system of Kuruktag and the crustal evolution in the early geological history. |
