Carbon isotope geochemistry of the Frasnian–Famennian transition

Palaeogeography, Palaeoclimatology, Palaeoecology, 2002
Abstract Carbon isotope records for inorganic and total organic carbon (TOC) as well as for individual organic biomarkers show two positive excursions in the Late Frasnian with comparable shape and amplitude in δ13C. The positive shifts in δ13C can be correlated with the deposition of the Kellwasser horizons.
