Formation

• The Aravalli formation, just like most mountain formation is explained based on plate tectonics collision in the Earth’s crust, much before the Himalayan formation.
• They were formed during the Aravalli–Delhi Orogeny involving the collision of microplates, which later became part of the Indian plate.
•  They extend from Gujarat to Delhi.
