Summary: To reveal the stratigraphic age of the Shiqianfeng Formation in the eastern continental basin of the North China Craton and the provenance of its sediments from the Late Carboniferous to the Early Triassic, six sandstone samples from the Puyang area were selected for zircon U-Pb dating. The result show that the Shiqianfeng Formation in the eastern North China Craton belongs to the Early Triassic. According to the age clusters of six samples, considering the regional geological setting and the distribution of zircon ages in the potential provenance area, it can be inferred that the Inner Mongolia Paleo-uplift provided continuous provenance supply for the study area during the Late Carboniferous-Early Triassic. It is also suggested that the Inner Mongolia Paleo-uplift originated during the Devonian and received denudation to provide provenance for inland basins. The second and third tectonic uplift occurred during the middle-late Permian, and the early-middle Triassic, respectively.
