| 摘 要： | 东疆哈尔里克造山带中红柱石的变形显微构造与区内A型俯冲引起的断裂区域变质作用有成因联系。红柱石的变形特征显示了其变形机制为塑性形变，处于韧性变形的条件下，表明变形前形成于一定的深度，后受推覆构造作用，发生变形并被带至地表，是区内构造演化的产物。

| Abstract: | The microfabric deformation structure of andalusite in the Harlik orogenic belt is genetically related to the faulting-induced regional metamorphism caused by intracontinental A-type subduction. The deformation characteristics of andalusite suggest that it belongs to plastic deformation under ductile metamorphic condition. It is shown that andalusite was formed at a deeper depth before deformation, then it was brought to the earth surface which was broken and deformed during large-scale thrust tectonism. It is the product of tectonic evolution in the area. |
