Abstract

Kaiho et al. report sulfur isotope and chemical data for samples from the Meishan (China) Permo-Triassic (P-Tr) boundary section. They interpret the S-isotope data, as well as the occurrence of Fe- and Ni-rich particles, as evidence for a large-scale impact event that penetrated the Earth’s mantle and formed a crater ~1000 km in diameter. We disagree with their interpretation in all major points.
