Abstract：The Upper Paleozoic Benxi Formation in the Ordos Basin experienced multiple transgressions and developed extensive epicontinental sea deposits. The distribution characteristics and control factors of the clastic barrier system in the southeastern of the basin are still not clear. Based on the field core,electric logging, and other data,this paper studied and established the sedimentary sequence of barrier system,restored the macro palaeogeomorphic features,depicted the plane distribution of barrier sand body,and clarify the migration style and control factors of the barrier system in Benxi Formation. Four types of sedimentary sequences,barrier island,tidal channel delta,tidal flat lagoon and swamp,were identified in the barrier coastal sedimentary system; moreover, two types of palaeogeomorphic features,namely,the stepped steep slope at the bottom of the Member 1 of Benxi Formation and the continuous gentle slope at the bottom of the Member 2 of Benxi Formation,were characterized. The barrier is distributed along the multi-stage parallel shoreline. the sand body continuity along the shoreline is high,and the vertical shoreline presents multi-stage migration characteristics. The barrier system shows two types of migration modes in map view. The Member 1 of Benxi Formation is dominated by rolling continuous migration,with low vertical overlap and strong horizontal continuity. The Member 2 of Benxi Formation is dominated by jump interval migration,with high overlap and weak horizontal continuity. The transgression process promoted the preservation of barrier system,but its distribution and migration were mainly controlled by palaeogeomorphology. The coastline trajectory controlled the distribution direction of the dominant long axis of barrier,and the steep and gentle slopes caused the differences in migration patterns of barriers. This study also emphasizes the importance of sea level rise and palaeogeomorphic slope in establishing the evolution model of ancient barrier systems.
