The Formation Mechanism and Geological Significance of Graptolite from the Longmaxi Formation: Constraints from in situ Multi-element Imaging Analysis
BACKGROUND The black shale of the Longmaxi Formation in the Upper Yangtze region is rich in graptolites. Most of them were preserved as a carbonaceous film, and enriched in organic-rich layers. Previous research focuses mainly on the graptolite morphology and evolution process after diagenesis, but...
