Rapid Emplacement of the Lower Deccan Traps and its Implications for Late Cretaceous Climate Change

The Deccan Large Igneous Province (LIP) is associated with the Crestaceous-Paleogene Boundary(KPB) mass extinction event at 66Ma. However, this is not the only environmental crisis it is linked to Petersen et al. 2016 show a regional warming and extinction event in Antarctica and Hull et al 2020 constrain an implied major volcanic outgassing event. Both are 250,000 years before the KPB. Such events suggest a sustained period of large volume of volcanic activity. The Thakurvadi Formation in the Kalsubai Sub-group, Deccan, is a prime candidate for this.
