| 摘 要： | 陕西圣人桥附近,复杂多样的褶皱出现在平缓的地台盖层之中。对其成因,争议颇多,或认为推覆作用所致,或认为受断裂作用控制。笔者通过详细研究,认为这些复杂褶皱是一种水底重力滑塌构造。据此,还提出了重力滑动构造新的分类,即重力蠕滑;重力滑塌以及重力滑碎等三类。

| Abstract: | Complicated and diversified folds are observed in the platform type of gentle covering strata near Shengrenqiao, Shaanxi province. There are a lot of controversies about the origin. It is thought that the folds were caused by napping, or it is regarded that they were controlled by regmagenesis. Through an exhaustive study the writers consider that it is a kind of gravity sliding structure underlain the underwater collapse.Based on this study, they put forward a new classification of the gravity sliding structures, i.e.gravity creep sliding, gravity sliding collapse, and gravity slip rupture. |
