Assumptions Regarding Former Stream Behaviour and Neo-Tectonism from Fluvial Terraces Along The Somesar River in Western Rajasthan, India

Abstract

A set of two fluvial fill-cut terraces have been identified along the Somesar river which originates from the Aravalli mountains and flows westward Detailed studies indicate that the terraces are not very wide, but still preserve some of the surficial distinguishing marks of the former stream courses on them, which suggest the recency of the terrace formation. A hypothetical evolutionary scheme has been put forward for the terraces on the basis of their morphology and stratigraphy. It has also been suggested that neo-tectonic activities have taken place along a series of faults in this region, which were responsible for the formation of terraces along the Somesar and some other rivers in the Aravalli foot-hills.
