Case in point: the Poladpur Formation, a key layer of Deccan Traps lava that both teams examined. Sprain's data allow for the Poladpur to have formed alongside or after the impact.

Here, researchers stand atop a massive basalt flow of the Mahabaleshwar Formation of the Deccan Traps at the Sinhagad Fort, located on a dramatic cliff in the Sahyadri Mountains.

However, the extinction also coincided with a burst of intense volcanic activity that formed a huge rock formation known as the Deccan Traps in western India.. Similar volcanic events have been ...

Knowledge and study of the Deccan Traps eruptions have consistently cast a shadow of doubt on the theory that the Chicxulub impact was the sole cause of the end-Cretaceous mass extinction, most ...

Deep drills into millions of years-old volcanic rock of the Deccan Traps in peninsular India have unearthed a teeming microbial community 1,500 metres below the earth’s surface. The array of ...

Geological History The Deccan traps formed during the eruption of a volcano that took place around 66 million years ago and resulted in the end of the Cretaceous period.

Over the course of 420,000 years following the asteroid, they concluded, the Deccan eruptions produced enough lava to cover the continental U.S. with a molten, 600-ft-deep (183 m) ocean.

Discovered in 2010 in Montana’s famed Hell Creek Formation of the late Cretaceous, ... But that notion depends a lot on more precise dating of the Deccan Traps and the Chicxulub crater.
