The Deccan Trap is a large volcanic plateau that covers most of the central and western Indian subcontinent. It is one of the largest igneous provinces on Earth, covering an area of about 500,000 square kilometers. The Deccan Trap was formed by a series of massive volcanic eruptions that occurred over a period of about 60 million years. The eruptions began in the Cretaceous period and continued into the Paleogene period. The Deccan Trap is composed of basalt, a type of volcanic rock. Basalt is a dark, fine-grained rock that is rich in iron and magnesium. The Deccan Trap is a significant geological feature because it is one of the largest and most well-preserved igneous provinces on Earth. The Deccan Trap is also important because it is thought to have played a role in the extinction of the dinosaurs. The Deccan Trap is exposed in the following states of India:
