Abstract
Undulation is one of the fundamental models of the geological effect , the undulation motion and variation inshape of earth crust is an geologic facts. In this paper, the undulation theory is applied to discuss the structure, de-posit and paleogeography pattern of Paleozoic of Ordos Basin. The units of wave structure of Ordos and its neigb-houring areas are divided as: Yinshan wave trough, Yimeng wave crest, Central wave trough, Weibei wave crest,Qingling wave crest, Alashan wave crest, Helan wave trough, Central doming wave crest, Eastern wave trough andKelan wave crest structure belt. The compound of Central wave trough and Eastern wave trough formed eastern saltdepression. This area has also formed the big center of hydrocabon source that are the most important in under Pa-leozoic group of Ordos Basin. Central doming wave crest structure belt and Central wave trough structure belt wereformed Dinbian compound areas, which make the central doming appear saddle in Dinbian. It also reasonably ex-plains the phenomenon that Central doming is suspended in Dinbian area.关键词
