Abstract:
To investigate the provenance, organic matter enrichment mechanisms, and paleoenvironmental evolution of Upper Permian Longtan Formation mudstone and shale in southern Sichuan, the Yuping section in Xingwen area was selected as a case study; based on systematic field investigations, sampling, and integrated analyses, including organic geochemistry, organic petrology, and major, trace, and rare earth element measurements, key paleoenvironmental parameters(source rock type, paleoclimate, paleosalinity, and redox conditions)during the deposition of Longtan Formation were characterized; the organic matter characteristics and paleoenvironmental evolution of the organic-rich mudstone and shale were elucidated, and the primary geochemical controls on organic matter enrichment were identified. The results indicate that Longtan Formation mudstone and shale from Yuping section are characterized by relatively high total organic carbon(TOC), averaging 3.80%; the maceral composition is dominated by vitrinite, and kerogen is predominantly type Ⅲ, suggesting a terrestrial higher plant origin and gas-prone source rock potential; the main provenance is attributed to high-Ti basalt from Emeishan large igneous province, with minor granitic input, consistent with an active continental margin setting; the average chemical index of alteration(CIA)of 83.90 reflects moderate to intense chemical weathering; paleoclimate proxies(averages of Sr/Cu and MgO/CaO ratios are 1.89 and 1.99)suggest generally warm and humid conditions; paleosalinity indicators(averages of Sr/Ba and 100MgO/Al2O3 ratios are 1.05 and 3.76)point to deposition in a brackish lacustrine environment; shallow-water, proximal deposition is supported by the average Zr/Al ratio(8.25×10-3)and 100MgO/Al2O3 ratio(0.66); redox proxies(averages of V/(V+Ni)ratio, Ni/Co ratio and Ceanom are 0.83, 4.77 and 0.04)indicate weakly reducing to reducing conditions. In summary, the organic-rich mudstone and shale of Longtan Formation in the southern Sichuan are deposited in a brackish, marine-terrestrial transitional setting under warm and humid climatic conditions. Within the geological context of Kangdian paleocontinent large igneous province, intense chemical weathering of Emeishan high-Ti basalts produces abundant fine-grained detritus. Concurrently, dense vegetation contributes substantial terrestrial organic matter, which is rapidly transported and buried in the sedimentary basin. High sedimentation rates limit the exposure of organic matter to oxygenated waters, while weakly reducing to reducing conditions further suppress organic matter oxidation, ultimately leading to the formation of high-quality, gas-prone organic-rich mudstone and shale.
