Uranium-lead ages from an ion probe were taken for zircons from the ore-bearing Noril'sk I intrusion that is comagmatic with, and intrusive to, the Siberian Traps. These values match, within an experimental error of �4 million years, the dates for zircons extracted from a tuff at the Permian-Triassic (P-Tr) boundary. The results are consistent with the hypothesis that the P-Tr extinction was caused by the Siberian basaltic flood volcanism. It is likely that the eruption of these magmas was… 
Paleomagnetism of the Siberian Flood Basalts of the Noril'sk Area: A Constraint on Eruption Duration
The volcanic sequence of the Noril'sk area, northern Siberia, provides the most complete section of early Siberian flood-basalt volcanism. Paleomagnetic measurements for more than 4000 samples of
The stability of the stratospheric ozone layer during the end-Permian eruption of the Siberian Traps
TLDR
An extended version of the Cambridge two-dimensional chemistry–transport model is used to evaluate quantitatively the possibility that the eruption of the Siberian Traps through older organic-rich sediments synthesized and released massive quantities of organohalogens, which caused widespread O3 depletion and allowed increased terrestrial incidence of harmful ultraviolet-B radiation.
Petrogenesis of the Flood-Basalt Sequence at Noril'sk, North Central Siberia
The 3500-m-thick sequence of volcanic rocks at Noril'sk, formed during a brief interval (∼1 m.y.) at the Permian/Triassic time boundary (∼251 Ma), represents the earliest part of the ∼6500-m-thick

Rapid Eruption of the Siberian Traps Flood Basalts at the Permo-Triassic Boundary
TLDR
Laser-heating 40Ar/39Ar data indicate that inception of Siberian Traps volcanism coincided with a profound faunal mass extinction at the Permo-Triassic boundary 249 � 4 million years ago; these data thus leave open the question of a genetic relation between the two events.
Flood Basalt Volcanism During the Past 250 Million Years
TLDR
There were 11 distinct episodes of major continental flood basalt volcanism during the past 250 million years, and the initiation dates of the episodes are close to the estimated dates of mass extinctions of marine organisms.
