Editing Deccan Traps (section)

===Chicxulub crater===
Although the Deccan Traps began erupting well before [[Chicxulub crater|the impact]], in a 2015 study it was proposed based on [[argon–argon dating]] that the impact may have caused an increase in permeability that allowed magma to reach the surface and produced the most voluminous flows, accounting for around 70% of the volume.<ref name=Richards2015>{{cite journal |last1=Richards|first1=Mark A. |last2=Alvarez|first2=Walter |last3=Self|first3=Stephen |last4=Karlstrom|first4=Leif |last5=Renne|first5=Paul R. |last6=Manga|first6=Michael |last7=Sprain|first7=Courtney J. |last8=Smit|first8=Jan |last9=Vanderkluysen|first9=Loÿc |last10=Gibson|first10=Sally A. |author-link2=Walter Alvarez |author-link5=Paul Renne |author-link6=Michael Manga |title=Triggering of the largest Deccan eruptions by the Chicxulub impact|journal=Geological Society of America Bulletin |volume=127|issue=11–12|pages=1507–1520 |doi=10.1130/B31167.1 |year=2015|bibcode=2015GSAB..127.1507R |s2cid=3463018 |url= http://eprints.esc.cam.ac.uk/3289/1/Gibson%20bul%20gsa.pdf |archive-url=https://web.archive.org/web/20180219045415/http://eprints.esc.cam.ac.uk/3289/1/Gibson%20bul%20gsa.pdf |archive-date=2018-02-19 |url-status=live}}</ref> The combination of the asteroid impact and the resulting increase in eruptive volume may have been responsible for the mass extinctions that occurred at the time that separates the Cretaceous and [[Paleogene]] periods, known as the [[K–Pg boundary]].<ref>{{cite journal |title=State shift in Deccan volcanism at the Cretaceous-Paleogene boundary, possibly induced by impact |last1=Renne |first1=P.
