Deccan Traps
The Deccan Traps are a large igneous province located on the Deccan Plateau of west-central India (between 17°–24°N, 73°–74°E) and one of the largest volcanic features on Earth. They consist of multiple layers of solidified flood basalt that together are more than 2,000 m (6,562 ft) thick, cover an area of 500,000 km2 (193,051 sq mi) and have a volume of 512,000 km3 (123,000 cu mi). ==Etymology== The term "trap" has been used in geology since 1785–95 for such rock formations. It is derived from the Scandinavian word for stairs ("trapp") and refers to the step-like hills forming the landscape of the region.〔(Trap ) at dictionary.reference.com〕
