| 摘 要： | 张宣地区的高级片麻岩地体褶皱样式从等斜的片内褶皱、与韧性剪切紧密伴生的构造，到脆性剪切，开阔褶皱和平缓的弯曲，经历了韧性－脆性的变形，根据构造叠加原理、利用构造间的相互关系可以确定其变形序列，并对断裂构造及其矿作用进行了探讨。

| Abstract: | High grade gneiss terrains have undergone ductile brittle deformation in Zhangxuan area. Fold styles ranging from isoclinal, intrafolial and open folds as well as broad warps through structures are colsely associated with ductile shear zones and brittle shear zones. The deformational sequences may be determined based on the principle of structural supposition. The fracture and its ore controlling structures are studied. |
