WebJul 17, 2024 · New simulations add to growing evidence that an asteroid strike, rather than the Deccan Traps eruptions, caused the end-Cretaceous extinction. WebNov 1, 2024 · An exception is the Deccan Traps LIP where the end-Cretaceous mass extinction is bracketed between trans-India lava flows (>1000 km long) (Keller et al., 2008, Keller et al., 2011, Keller et al., 2012; Self et al., 2008). 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 (… king evelthon beach hotel and resort opinie
