Correct Answer: C
Solution :
Deccan traps are formed by vast outpouring of basic lava from many linear fissures developed in the earth's crust. This outpouring was of quiet type and hence did not create any volcanic domes. It just spread across the surface. This outpouring was in many active stages followed by periods of quiescence. This outpouring took place around 65 million years ago when India was near present placed Madagascar and during its movement towards north, it passed over Reunion Hotspot. Presently this hotspot is dormant in nature. This outpouring lasted for 5million years approx. according to latest study.You need to login to perform this action.
