More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year.

Deccan Traps - Wikipedia
The Deccan Traps is a large igneous province of west-central India (17–24°N, 73–74°E). They are one of the largest volcanic features on Earth.
