The fourth and final suggestion that paleontologists have formulated credits the Permian mass extinction as a result of basaltic lava eruptions in Siberia. These volcanic eruptions were large and sent a quantity of sulphates into the atmosphere. Evidence in China supports that these volcanic eruptions may have been silica-rich, and thus ...Ocean acidification and mass extinction.

The Permian (/ ˈ p ɜːr m i. ə n / PUR-mee-ən) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period 298.9 million years ago (Mya), to the beginning of the Triassic Period 251.902 Mya. The end-Permian mass extinction (EPME) is marked by ∼80% marine biodiversity loss ( 1 ).
