关于编制盆地构造演化剖面的几个问题的讨论

本文根据平衡剖面原理,从构造地质学基本原理出发,讨论了采用“地层回剥”方法编制构造演化剖面时遇到的影响古构造复原的若干问题,强调建立平衡地质剖面和利用平衡剖面技术编制盆地构造演化剖面时,“地质概念上”的平衡和地质逻辑上的合理比纯粹的“几何学上”的平衡更重要。

Some Problems about Compiling Tectonic Evolution Sections of Basin

The idea and technique are both important in the process of compiling basin evolution sections. As compilers may give different interpretations to the same tectonic section and use different ideas and techniques in map making, the characteristics of paleo-tectonics in basin evolution sections in the same area may be utterly different. According to the principle of the balanced geological cross-section and theory of structural geology, this paper discusses some problems that may affect the reconstruction of paleo-tectonics when using the " back stripping" method in constructing the tectonic evolution sections. The authors emphasize that "geological conceptual balance" is more important than pure "geometric balance" in the constructiont of balanced geological cross--section and compilation of tectonic evolution sections by using the balanced section technique
