Sediment provenance of Late Carboniferous-Early Triassic in the Puyang area, Eastern North China Craton.

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.

A study on the accumulation model of the Santos basin in Brazil utilizing the source-reservoir dynamic evaluation method.

The exploration potential within deep-water petroliferous basins holds great promise for oil and gas resources. However, the dearth of geochemical and isotopic data poses a formidable challenge in comprehending the intricate hydrocarbon charging processes, thereby impeding the comprehensive understanding of hydrocarbon accumulation mechanisms and models. Consequently, the establishment of robust source-reservoir relationships in deep-water petroliferous basins represents a pivotal challenge that significantly influences the exploration strategies and the comprehension of hydrocarbon enrichment dynamics within such basins.
