Astronomical control on upper ordovician – lower silurian organic matter enrichment in South China

Astronomical control on upper ordovician – lower silurian organic matter enrichment in South China

Astronomical forcing governed Late Ordovician–Early Silurian climate dynamics, yet high-resolution Astronomical Time Scales (ATS) and organic enrichment mechanisms during the end-Ordovician extinction remain poorly constrained. In this study, we integrated gamma ray (GR), δ13Corg, and chemical index...
