Peninsular Block, Himalayan Region, and Indo-Gangetic Plains: Comparative Features
The Indian landmass exhibits remarkable physiographic diversity shaped by differential geological evolution and tectonic forces. The Peninsular Block, the Himalayan Region, and the Indo-Gangetic Plains, each represents a unique stage of Earth’s structural history. Together, these regions form a tripartite division reflecting India’s transition from ancient stability to young tectonic dynamism and fluvial deposition.
Geological Background
- The Peninsular Block represents the ancient stable shield of the Indian landmass formed during the Archaean and Proterozoic eras.
- The Himalayan Region is geologically young and unstable, created by the collision of the Indian and Eurasian plates around 50–60 million years ago.
- The Indo-Gangetic Plains are ....
