40 Ar-39 Ar age of a lava flow from the Bhimashankar Formation, Giravali Ghat, Deccan Traps

Journal Article

We report here a 40Ar-39Ar age of 66.0 ± 0.9 Ma (2σ) for a reversely magnetised tholeiitic lava flow from the Bhimashankar Formation (Fm.), Giravali Ghat, western Deccan province, India. This age is consistent with the view that the 1.8-2 km thick bottom part of the exposed basalt flow sequence in the Western Ghats was extruded very close to 67.4 Ma. © Printed in India.
