| 摘 要： | 大青山早前寒武纪高级变质岩系中发育三种不同类型的韧性剪切带。第一种为高温（相当于麻粒岩相级）逆冲型，第二种为中温（相当于角闪岩相级）伸展型，第三种为低温（相当于绿片岩相级）近走滑型。不同类型韧性剪切带的变形变质作用演化反映了地壳深部高级变质杂岩在隆升过程中的主要再造特征。

| Abstract: | Three types of ductile shear zones are recognized in the early precambrian high grade metamorphic complex in Daqingshan area. The first is characteristic of high temperature (correspond to granulite facies grade) and thrusting, and the second is middle temperature (correspond to amphibolite facies grade) and stretching, the third is low temperature (correspond to greenschist facies grade) and near strike slipping. The deformational metamorphic evolution of the three types of the ductile shear zones reflects the main reworking during the uplift processes of the deep crustal high grade metamorphic complex. |
