浅变质岩区非整体变形和滑动构造初探

A PRELIMINARY STUDY ON NON-HARMONIC DEFORMATION AND SLIDING STRUCTURES IN LOW-GRADE METAMORPHIC AREA

在分析了陕西旬北浅变质沉积岩区、甘肃白银厂浅变质火山—沉积岩区的构造变形特征的基础上 ,得出了构造变形非整体性的认识 ,进而提出构造变形单元体的概念和划分依据 。

Taking Xunyang in Shaanxi (a low grade metamorphic sedimentary area) and Baiying in Gansu (a low grade metamorphic volcano sedimentary district) as examples, the paper analyzed the characters of non harmonic structural deformation. Based on it, the non harmonic structural deformation, the structural deformation unit and inter layer sliding structure in low grade metamorphic areas were presented, and their field features and discernment discussed.
