一、前言我们在实际地质工作中,特别是在1∶1万和1∶5千地质测量工作过程中,在倒转地层地区工作时,经常迂到一些地质构造的褶曲问题。这些褶曲与正常地层中的褶曲不一样。一般说来,背斜核部由老岩层组成,向斜核部由新岩层构成,而在倒转地层中恰恰相反,即背斜核部由新岩层组成,向斜核部由老岩层构成,其构造形态还是背、向斜外形。为了弄清这些问题,我们提出一些粗浅看法,介绍一些实际资料,和同志们共同讨
I. INTRODUCTION In actual geological work, especially in 1: 10000 and 1: 5000 geodetic surveys, we often circle the folding problems of some geological formations while working in the inversion stratigraphic area. These folds are not the same as the folds in normal formations. In general, the anticline core consists of an old rock formation, the syncline core consists of a new rock formation, whereas in the inversion formation the opposite is true, ie the anticline core consists of a new rock formation and the syncline core consists of an old rock formation whose Structure form or back, oblique shape. In order to clarify these problems, we have put forward some superficial views, introduced some actual materials and jointly discussed with the comrades
