片理（劈理）为早世代挤压-剪切褶皱的轴面片理，又成为晚世代弯滑褶皱的滑动面；

The cleavage and schistosity acted as an axial plane role in the early generation of compressed shear fold, and changed into a slip plane in the later generation of flexural slip fold.

主要容矿构造为剪切带和褶皱，其类型有轴面劈理型、片理型和滑脱面型，矿体组合样式有斜列式、“S”形和“乡”字形、“H”形及网格形等。

Structures controlling the orebodies include plane cleavage, schistose cleavage and decollement plane, and the orebodies usually arrange in the form of "S", "H" or grid, and so on.
