轴面劈理是指其产状平行于或大致平行于褶皱轴面的劈理。这类劈理主要发育在强烈褶皱的岩层里。轴面劈理和轴面片理的产状与褶皱轴面的关系取决于组成褶皱岩石的韧性、均一性和褶皱的形态。在岩性均一、平均韧性高、韧性差小的岩系里，轴面劈理与轴面的平行性也愈高。
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.
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.
