- •
The Central Indian Tectonic Zone (CITZ) is a sector in a series of Paleoproterozoic orogens of the supercontinent Columbia.
- •
The present study reveals that the Mahakoshal belt of CITZ was formed as a back arc rift within the Bundlekhand craton.
- •
The Mahakoshal back arc rift was developed by trench roll back.
- •
After the cessation of volcanism, it was followed basin inversion and sediments started supply from the continental arcs.
- •
The present study reveals the subduction - related outgrowth of CITZ similar to continental margins of Columbia.
