在多级组合的褶皱群(系)中,如何研究褶皱形态及其组合规律,以及由此所控制的地层产状和矿层联结,是大比例尺地质测量和变质层状矿床评价中的一个复杂课题。然而通过对褶皱包络面(Fold fatehspiege)的研究,为解决上述问题提供了一个重要途径。 In the multi-level assemblage fold system, how to study the fold shape and its combination rule, and the strata-formation and ore-seam association controlled by it are a complex issue in the evaluation of large-scale geological surveys and metamorphic bedded deposits . However, through the research on Fold fatehspiege, it provides an important way to solve the above problems.
