摘要
本文从构造变形和断层岩的角度,运用断裂构造的新观念.通过野外宏观特征和糜棱岩的显微构造研究,证实了彭灌杂岩体中韧性剪切蒂的存在,并以构造层次原理阐述了它们对该区构造研究的意义。
Applying new conceptions on fault structure and based upon research on both characteristics of macrostructure and microstructure of mylonite ,it is believed that ductile shear zones exist in Proterozoic complex granite mass in the middle segment of Longmen mountains. Their significance for structure study in this area is also discussed in the paper.
