DOI: 10.1021/acsomega.3c00273
Abstract: Although previous studies have yielded valuable insights into shale gas reservoirs, a comprehensive understanding of the organic geochemical characteristics and organic matter enrichment of marine–continental transitional shale has yet to be achieved. The Longtan Formation… read more here.

DOI: 10.3390/min9080467
Abstract: The occurrence of pyrite concretions in the Permian Longtan Formation sheds light on the paragenesis, formation conditions and regional paleoenvironment. We analyzed the mineral and geochemical characteristics of pyrite concretions using scanning electron microscopy-energy dispersive… read more here.
