Biotite separates from three granite plutons in the Northern part of the Kerala region, namely, Kalpatta. Ambalavayal and Thaluru yield K-Ar ages of 512±20 m.y., 560±30 m.y. and 710±20 m y. respectively. The age data are comparable with those reported for similar granitic intrusives of the south Indian region.

Abstract


Biotite separates from three granite plutons in the Northern part of the Kerala region, namely, Kalpatta. Ambalavayal and Thaluru yield K-Ar ages of 512±20 m.y., 560±30 m.y. and 710±20 m y. respectively. The age data are comparable with those reported for similar granitic intrusives of the south Indian region.
