Abstract: The formation and destruction of the North China Craton has always been a hotspot in global geology research, the tectonic setting has been widely study in the Precambrian and Mesozoic, but the Paleozoic has still relatively poor. Objectives In order to discusses the evolutionary process of basin-orogeny systems in the North China Basin and surrounding orogens in the Late Paleozoic. Methods This paper collected the published U-Pb age data of the Late Paleozoic detrital zircons in the North China Basin, by conducting large-scale data collation and statistics, and combined with the evolution process of surrounding orogenic belts. Results The detrital zircon from the Benxi Formation of the North China Basin in the Late Carboniferous had two major age group peaks at 310 Ma, 440 Ma. The detrital zircon from the Taiyuan Formation-Upper Shihezi Formation of the Early Permian had five major age group peaks at 310 Ma, 300 Ma, 440 Ma, ~1850 Ma, ~2500 Ma. The detrital zircon from the Shiqianfeng Formation of the Early Permian had five major age group peaks at 260 Ma, 310 Ma, 440 Ma, ~1850 Ma, ~2500 Ma. Conclusions In the Late Carboniferous, the main provenance of the North China Basin is thought to be the Qinling Orogenic Belt. In the late Early Permain, The sediments from Inner Mongolia uplift are distributed in the northern margin of the North China Basin; the sediments of the Inner Mongolia uplift prograde to the southern of the North China Basin, the tectonic pattern had been transformed from high in the south to high in the north in this time. Qinling Orogenic Belt provide sediments to North China Basin again in the Late Permain, indicate the uplift of the southern of the basin. The evolution of the provenance indicates the continuously enhanced orogenic movement of Xingmeng Orogenic Belt of the northern of North China and the tectonic transformation of extension-subduction of the Mianlue Ocean in Qinling Orogenic Belt of the southern of the North China.
