The Igneous Deccan Traps

My friend and I visited the Deccan Traps located in west-central India. The Deccan Traps cover a massive area of around 200,000 square miles. In some areas, temples and shrines have been carved right into the rock. The Traps are composed of extrusive basalt rock which formed from lava flows that are estimated to have originally covered an area of up to 600,000 square miles. When it comes to rock composition, the Traps are not very unique, being composed mostly of the dark-colored fine-grained mafic rock basalt, which is the most common extrusive rock. However, the scope of the lava flows that created this area is astounding. There are even theories that volcanic activity that created the area may have led to the extinction of the dinosaurs.
