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

德干大火成岩省（LIP）与66Ma的冠西纪-古近纪界线（KPB）大灭绝事件有关。然而，这并不是唯一与Petersen等人有关的环境危机。2016年显示了南极洲的区域变暖和灭绝事件，Hull等人2020年限制了隐含的主要火山排气事件。两者都比KPB早25万年。这些事件表明有一段持续的大规模火山活动时期。德干地区Kalsubai亚群中的Thakurvadi组是一个主要的候选组。

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.
