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… Expand
