NARMADA HYPOTHESIS

Formation of Satpura Ranges

The presence of Narmada goes way back when the Asian and Australian plate was still one landmass. An educational insight “The benevolent Narmada River” mentions the existence of Dinosaurs on the banks for communal nesting. Several fossils from the cretaceous era have been found around the valley.

When the Indian tectonic plate collided with the eurasian plate , Australia broke off from Asia and floated to the southern seas. Indian Peninsular plate was formed due to the collision of three protocontinents : Aravalli , Dharwad and Singhbhum. That was the time when the Satpura ranges were forming. Some parts of the ranges between the Narmada Tapi lineament are considered to be Horst mountains , while some parts are considered Fault Mountains.

The fossil records around these mountains and valleys give evidence of the presence of Narmada Valley in prehistoric times.

One more way to understand the formation of the valley while being a part of the great african plate is the movement of Intra-continental plates. When the tectonic plates move one of the three things happen. They either come towards each other , or converge; move away from one another, or diverge; or slide past one another, a movement known as transform motion.

The southern boundary of the Satpura range, with the Tapi valley,is marked by a steep, ~1 km high scarp. This imposing scarp running for hundreds of kilometers is considered a major normal fault bounding the Satpura horst.
