Critical evaluation of the age of the Deccan Traps, India; implications for flood-basalt volcanism and faunal extinctions

Attempts to evaluate the possible link between flood-basalt volcanism and the faunal extinctions observed at the K/T boundary must rely on precise knowledge of the amount of such volcanism that took place 65 Ma. The current geochronological data do not permit close resolution of either the timing or...

description Attempts to evaluate the possible link between flood-basalt volcanism and the faunal extinctions observed at the K/T boundary must rely on precise knowledge of the amount of such volcanism that took place 65 Ma. The current geochronological data do not permit close resolution of either the timing or the duration of Deccan volcanism; the age of the bulk of the material is placed in the range 70-60 Ma. Further resolution of this hypothesis awaits acquisition of high-quality 40Ar-39Ar plateau ages on key sections of the Deccan Traps.
