The Lower Triassic sedimentary and carbon isotope records from Tulong (South Tibet) and their significance for Tethyan palaeoceanography

As for many other Tethyan localities the carbon isotope record from Tulong is characterized by a late Griesbachian-Dienerian positive δ13Ccarb excursion (2‰), and a very prominent positive excursion (5‰) at the Smithian-Spathian boundary, thus confirming the well-documented perturbations of the global carbon cycle following the Permian-Triassic mass extinction event.
