///The authors have developed a method, by combining the spatial database analysis and the single-factor mapping technology, to establish sequence stratigraphical succession and to map the Ordovician litho-paleogeography of the Ordos Basin. By using the method, all of the related basic geological data can be quantitatively analyzed and scientifically managed. Various attributes of the basic stratigraphic units and their characters can be fully utilized statistically in facie analysis and in mapping. Based on this analysis, the authors have exerted single-factor isopachous mapping quantitatively for each of the Ordovician sequences in the basin, and finally synthesized multiple factors to construct the litho-palaeogeographical maps for each of the sequence intervals. The study shows that the proposed method is quite effective and has much higher resolution in recognizing litho-paleogeographic units than traditional ways.
