Marine Anoxia and Ocean Acidification During the End-Permian Extinction:An Integrated View From δ 238 U and δ 44/40 Ca Proxies and Earth System Modeling
The largest mass extinction event in the Phanerozoic, known as the end-Permian mass extinction (or EPME, ca. 252 Ma) is coincident with the main eruption phase of Siberian Traps volcanism (ca. 252 to 250 Ma), a large igneous province (LIP). This LIP is estimated to have a volume larger than 2 × 10 6...

The largest mass extinction event in the Phanerozoic, known as the end-Permian mass extinction (or EPME, ca. 252 Ma) is coincident with the main eruption phase of Siberian Traps volcanism (ca. 252 to 250 Ma), a large igneous province (LIP). This LIP is estimated to have a volume larger than 2 × 10 6 km 3 and to have released both mantle carbon dioxide (CO 2 ) through extrusions and thermogenic methane (CH 4 ) and carbon dioxide (CO 2 ) through intrusions. The climatic consequences of these greenhouse gases is detrimental to both marine and terrestrial life and may have delayed the recovery of ecosystems after the extinction. Quantitatively, the amount of CO 2 released can be estimated using global carbon (C) cycle model or plant and soil-based proxies with varying time resolution. In light of the recent advances in geochemical proxies of ocean anoxia and acidification, we review the latest uranium isotopes (δ 238 U) and calcium isotope (δ 44/40 Ca) records and Earth system modeling results to summarize the environmental response to the forcing of increased atmospheric CO 2 concentrations.
