Age and duration of the Deccan Traps, India: A review of radiometric and paleomagnetic constraints
A review of the available radiometric and paleomagnetic data from the Deccan Flood Basalt Province (DFBP) suggests that the volcanism was episodic in nature and probably continued over an extended duration from 69Ma to 63Ma between 31R and 28N. It is likely that the most intense pulse of volcanism at 66.9 ± 0.2Ma preceded the Cretaceous Tertiary Boundary (KTB, 65.2 ± 0.2Ma) events by ∼1.7Ma. The magnetostratigraphic record in the Deccan lava pile is incomplete and it is therefore possible that the lava ows constituting the reverse polarity sequence were erupted in more than one reversed magnetic chron.
