Summary:40Ar/39Ar age spectra for Deccan basalts are briefly reviewed, and though many samples are too altered to yield reliable plateau ages, five successful determinations confirm that most Deccan eruptions occurred during a relatively short period, from 65 to 69 m.y. This period may have coincided with the Cretaceous/Tertiary boundary, and could have been the largest volcanic event in Mesozoic and Cainozoic times. [R.K.H.]
