*3.4.1 Basalt*

The basaltic existence of the dyke is found within the tuff and iron oxides encrusted porphyritic dark brown rhyolite in the Maini and Sewadiya hills. Basalt is observed in both the flow and the dyke shape. The color is black, fine grained with small (few cm) vesicles. The basalt dyke is 2 meters wide and 10–15 meters long.
