如何测定不对称褶皱和任意类型褶皱的轴面位置及产状,一直被地质工作者所重视。本文仅就这个问题作一简述,并提出利用正交剖面(垂直枢纽的面)与极射赤平投影结合的方法来测定。该方法不仅适用于测定各种简单或复杂的轴面。而且还可用来研究轴面的位置及产状在地下不同深度的变化,用这种方法研究轴面的位置及产状,将在矿床勘探和工程地质中起到重要的作用。
How to determine the axial position and occurrence of asymmetric folds and any type of folds has been paid great attention by geologists. In this paper, only a brief description of this issue, and proposed the use of orthogonal cross-section (vertical hinge surface) and the combination of polar projection stereotypes to measure. This method is not only suitable for measuring a variety of simple or complex axis. But also can be used to study the change of the location of the axial surface and its occurrence in the underground depth. Using this method to study the location and occurrence of the axial surface will play an important role in prospecting and engineering geology.
