Rajmahal highlands consist of multiple layers of lava flow deposits which is predominantly tholeiitic basalt, quartz tholeiite, olivine tholeiite and alkali basalt. Bundelkhand is the part of peninsular Plateau which is one of the oldest landforms of earth. It is a highly stable block composed mostly of the Archaean gneisses and schists.
