WebFeb 21, 2024 · Schoene and his colleagues suggest the Deccan eruptions occurred in four bursts. The second was the most rapid and it began tens of thousands of years before the asteroid impact. WebMassive volcanic eruptions in the region of the Deccan Traps in present-day India occurred at around the same time as the asteroid impact. The enormous volumes of lava, ash and gases released during these eruptions would have caused massive climate change, leading to significant cooling and extinction of many species, including the dinosaurs.
The release of volcanic gases, particularly sulfur dioxide, during the formation of the traps may have contributed to climate change. An average drop in temperature of about 2 °C (3.6 °F) was recorded during this period. Because of its magnitude, scientists have speculated that the gases released during the formation of the Deccan Traps played a major role in the Cretaceous–Paleogene (K–Pg) extinction event (… WebMar 4, 2024 · Fact: About 66 million years ago, a massive volcano erupted lavas in India that are now called the Deccan Traps, burying much of the subcontinent under more than 11,000 feet of basalt (lava rock) and …

If sulfur gases were an important component of the early eruptive phase of the Deccan Traps prior to the impact, it is likely they were limited to tropospheric sulfur aerosols, which have relatively short residence times (weeks ... WebFeb 21, 2024 · For the next 750,000 years, the volcanoes unleashed about 80-90 percent of the Deccan Traps’ total lava flows and were ongoing at the time of the end-Cretaceous mass extinction.
WebDeccan Traps are made up of multiple flood-basalt deposits from eruptions that happened between 67 and 63 million years ago. Given the long duration of the Deccan eruptions, many researchers expected to the extinction rate rise 67 million years ago and to continue being high for millions of years.
