The Deccan Traps are a large igneous province of west-central India (17–24°N, 73–74°E). They are one of the largest volcanic features on Earth, taking the form of a large shield volcano. [2] .
The Deccan Traps date back to around 66 million years ago, when magma from deep inside Earth erupted to the surface. In some parts of the Deccan Traps, the volcanic layers are more than two kilometers (1.2 miles) thick, making this the second-largest volcanic eruption ever on land.
Deccan Traps Volcanic Mountains in western India near Pune. Deccan eruptions accumulated over 350,000 years in horizontal Lava flows covering an area the size of France to a height of 3400 m. Eruptions occurred in pulses resulting in global climate warming.
The Deccan Traps are one of the largest volcanic provinces in the world. It consists of a composite thickness of more than 6,500 feet (>2,000 m) of flat-lying basalt lava flows and covers an area of nearly 200,000 square miles (500,000 square km) (roughly the size of the states of Washington and Oregon combined) in west-central India.
There was once a time when much of India was coated in an active layer of lava more than a mile thick.
theories about cause of the K–T extinction. …of lava, known as the Deccan Traps, occurred in India at the end of the Cretaceous. Some paleontologists believe that the carbon dioxide that accompanied these flows created a global greenhouse effect that greatly warmed the planet.
The Deccan Traps and Reunion hotspot track are well explained as melting of delaminated, recycled continental mantle lithosphere and a propagating crack.
However, scientists have long wondered about the massive volcanic eruptions that were occurring in India at about the same time, the Deccan Traps. Volcanism is the likely cause of several prior mass extinctions, with no convincing evidence for impacts.
The Deccan Trapps (or Traps) are a volcanic plateau, or a large igneous province located in west-central India. It is generally believed that the traps formed through melting of a large mantle plume beneath the Indian continent.
The Indian subcontinent is blanketed with the remnants of at least five continental flood basalt provinces ranging in age from the Middle Proterozoic to the Late Cretaceous-Early Tertiary. Not surprisingly, the youngest of these, the Deccan plateau (derived from a...
