Abstract: The discussion about restoration of the primary Ordos basin during various of sedimentary periods in Mesozoic, have been paid more attention for a long time, but the degrees of cognition and study are different. Among them the study on that of Zhiluo-Anding Formation is especially weaker. Considering the trait of large depression basin in Ordos craton as well as the characteristic of its evolution and reconstruction, according to two aspects that the residual sedimentary entities and tectonic framework nowadays of the basin and its adjacent areas, and basing on a great deal of outcrop observation, drilling and logging data analysis and experimental test, through the systemic stratigraphic partition and compare, sedimentary facies analysis, multidisciplinary analysis of provenance, and the formation and evolution history analysis of the adjacent tectonic units, this paper argued that the original sedimentary boundary of the basin during the Zhiluo-Anding formations is approximately concluded: The eastern borderline is to the west of Taihangshan; the northern borderline lie is in Cenozoic Hetao basin; the north-westerm borderline lie in Langshan-Bayanhaote basin-Kexueshan; the north-easterm borderline lie in the west of the Liupanshan; the southern borderline reach to nowadays’ Weihe Cenozoic basin. From the basin’s periphery to the centre of lake basin, there were about 7 directions that supply the provenance, and the depocenter locate in the centre of primary basin by south. The basin’s evolution in this stage recorded the transition process and time limit of the North China Craton’s differentiation that from north-south differentiation in Indo-Chinese epoch to west-east differentiation in Yanshan-Epoch. This study provided geological evidences for establishing intact temporo-spatial coordinates of the Mesozoic basin’s evolution and the exploration assessment of energy minerals, such as uranium deposit and petroleum.
