Geochemistry of Middle Permian lacustrine shales in the Jimusar Sag, Junggar Basin, NW China: Implications for hydrothermal activity and organic matter enrichment
Journal of Asian Earth Sciences(2022)
摘要
•Intensive hydrothermal activity occurred during the deposition of the Lucaogou Formation.•The enrichment of both Sr and Li in the shales is consistent with a hydrothermal origin.•Hydrothermal activity supplied nutrients that enhanced paleoproductivity.
