摘要

Abstract

The Late Carboniferous–Early Permian was a period of profound paleoenvironmental transformation

yet the depositional response in the South Yellow Sea Basin (SYSB) on the eastern South China Block remains insufficiently understood. This study integrates petrographic

mineralogical (XRD)

and geochemical (major and trace element) data from Well CSDP-2 to reconstruct

palaeoweathering

paleoclimate

redox conditions

salinity

terrigenous influx

and paleobathymetry across the Chuanshan

Huanglong

and Gaolishan formations. Geochemical proxies—including CIA

Sr/Cu

V/Cr

U/Th

and Sr/Ba—reveal a stratigraphic transition from a high weathering

warm-humid

brackish

high-energy shelf with predominantly oxic conditions (Gaolishan) to weak weathering

cold-arid

deeper marine carbonate platform characterized by more reducing

intermittently anoxic conditions (Chuanshan). Microfacies analysis identifies seven carbonate facies ranging from restricted platform interiors to high-energy shoals. Principal component and cluster analyses delineate mineralogical differentiation aligned with stratigraphic boundaries and depositional environments. These findings document a long-term transgressive trend accompanied by climatic deterioration and evolving redox conditions. This study provides the first integrated

high-resolution reconstruction of Late Paleozoic paleoenvironmental dynamics in the SYSB

offering critical insights into marginal basin evolution during a pivotal interval of global climate change and contributing to broader paleogeographic reconstructions of the South China Block.
