Persistent late Permian to Early Triassic warmth linked to enhanced reverse weathering
In the Precambrian, reverse weathering—a process consuming oceanic silica, metal cations
and alkalinity to form marine clays—was a key control of the long-term carbon cycle …

Two distinct episodes of marine anoxia during the Permian-Triassic crisis evidenced by uranium isotopes in marine dolostones
The end-Permian mass extinction (EPME; ca. 251.94 Ma) is the most severe mass extinction
in the geological record. Detailed paleobiological investigations show a very rapid EPME …
