学科：构造地质学 词目：褶皱轴面 英文：axial surface of fold 释文：褶皱轴面是由一组相邻褶皱面的枢纽连成的面。对称褶皱或两翼岩层厚度基本相同的褶皱中，轴面是翼间角的平分面，或是大致平分褶皱两翼的对称面。轴面可以是平面或曲面，如为平面亦称为轴平面（axial plane）。
如果褶皱构造的轴面基本上是水平的，那么我们称它为平卧褶皱。
If the axial plane of a fold is essentially horizontal. Then we call it recumbent fold.
主要遵循4个基本步骤，轴面分析是基础，断层褶皱形态分析是核心，平衡观念是灵魂，构造复原是手段。
The structural model should be built in 4 steps with the axial surface analysis as the basis, the fault-fold geometric analysis as the key, the balanced idea as the guidance and the stru.
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.
