The Meghalaya plateau is traditionally divided into Garo, Khasi and Jaintia Hills.
Its link with the Meghalaya plateau proper is towards the south through a patch of highly denuded and subdued senile terrain.
[2] It is believed that due to the force exerted by the northeastward movement of the Indian plate at the time of the Himalayan origin, a huge fault was created between the Rajmahal hills and the Karbi-Meghalaya plateau.
Later, this depression was filled up by the depositional activity of numerous rivers.
Today the Maghalaya and Karbi Anglong plateau remains detached from the main Peninsular block.
