Concept:The Meghalaya Plateau is an extension of the Deccan Plateau beyond the Rajmahal Hills.
Explanation:The Meghalaya region (also known as the Shillong plateau) is structurally a part of the Deccan Plateau of peninsular India.
The Deccan Plateau extends eastward beyond the Rajmahal Hills into Meghalaya.
The Garo-Rajmahal Gap separates the Meghalaya plateau from the main Deccan block.
This gap was formed by down-faulting and later filled with sediments from the Ganga and Brahmaputra rivers.
The plateau is composed of Archaean rocks such as quartzites, shales, and schists.
It slopes northward to the Brahmaputra valley and southward to the Surma and Meghna valleys.
Its western boundary coincides with the Bangladesh border.
The western part is the Garo Hills, the central part is the Khasi–Jaintia Hills, and the eastern part is the Mikir Hills.
Shillong is the highest point of this plateau.
