}The Siberian Traps represent one of the most voluminous flood basalt provinces on Earth. Laser-heating 40Ar/39Ar data indicate that the bulk of these basalts was erupted over an extremely short time interval (900,000 � 800,000 years) beginning at about 248 million years ago at mean eruption rates of greater than 1.3 cubic kilometers per year. Such rates are consistent with a mantle plume origin. Magmatism was not associated with significant lithospheric rifting; thus, mantle decompression…

Synchrony and Causal Relations Between Permian-Triassic Boundary Crises and Siberian Flood Volcanism
- Geology, MedicineScience

Analysis of 40Ar/39Ar data from two tuffs in southern China yielded a date comparable to the inception of main stage Siberian flood volcanism at 250.0 � 0.2 million years ago for the Permian-Triassic boundary.
40Ar/39Ar Dates from the West Siberian Basin: Siberian Flood Basalt Province Doubled
- Geology, MedicineScience

The age and geochemical data confirm that the West Siberian Basin basalts are part of the Siberian Traps and at least double the confirmed area of the volcanic province as a whole, which strengthens the link between the volcanism and the end-Permian mass extinction.

The results are consistent with the hypothesis that the P-Tr extinction was caused by the Siberian basaltic flood volcanism and may have been caused by a combination of acid rain and global cooling as well as rapid and extreme changes in sea level resulting from expansion of the polar ice cap.

The Cretaceous-Tertiary Transition

It seems more likely that an explanation for the changes during the Cretaceous-Tertiary transition will come from continued examination of the great variety of terrestrial events that took place at that time, including extensive volcanism, major regression of the sea from the land, geochemical changes, and paleoclimatic and paleoceanographic changes.
