Deccan Trap is a thick sequence (3200 metres) of late cretaceous basaltic lava flows that cover about 500000 sq. km. of peninsular India. Due to erosion this basaltic lava soil has been eroded step wise which is often termed as Deccan trap. This Deccan trap is widely prevalent in Deccan plateau, covering Saurashtra, Maharashtra, Karnataka parts of Tamil Nadu and Andhra Pradesh. Its thickness is not uniform rather it is somewhere deep and somewhere shallow depending on the surface whether flat or sloppy.
