Two timelines for extinction The Cretaceous-Paleogene extinction that wiped out the nonavian dinosaurs 66 million years ago was correlated with two extreme events: The Chicxulub impact occurred at roughly the same time that massive amounts of lava were erupting from the Deccan Traps (see the Perspective by Burgess). Sprain et al. used argon-argon dating of the volcanic ash from the Deccan Traps to argue that a steady eruption of the flood basalts mostly occurred after the Chicxulub impact… 

Eruption Rates, Tempo, and Stratigraphy of Paleocene Flood Basalts on Baffin Island, Canada

High‐temperature melting in mantle plumes produces voluminous eruptions that are often temporally coincident with mass extinctions. Paleocene Baffin Island lavas—products of early Iceland mantle

An evaluation of Deccan Traps eruption rates using geochronologic data

Abstract. Recent attempts to establish the eruptive history of the Deccan Traps large igneous province have used both U−Pb (Schoene et al., 2019) and 40Ar/39Ar (Sprain et al., 2019) geochronology.

Contribution of orbital forcing and Deccan volcanism to global climatic and biotic changes across the Cretaceous-Paleogene boundary at Zumaia, Spain

Untangling the timing of the environmental effects of Deccan volcanism with respect to the Chicxulub impact is instrumental to fully assessing the contributions of both to climate change over the

On impact and volcanism across the Cretaceous-Paleogene boundary

Carbon cycle modeling and paleotemperature records are used to constrain the timing of volcanogenic outgassing and found support for major out gassing beginning and ending distinctly before the impact, with only the impact coinciding with mass extinction and biologically amplified carbon cycle change.

State shift in Deccan volcanism at the Cretaceous-Paleogene boundary, possibly induced by impact

High-precision dating of Deccan Traps volcanic units suggests an increase in volcanism associated with the Chicxulub impact, which suggests postextinction recovery of marine ecosystems was probably suppressed until after the accelerated volcanism waned.

U-Pb geochronology of the Deccan Traps and relation to the end-Cretaceous mass extinction

U-Pb zircon geochronology is applied to Deccan rocks and it is shown that the main phase of eruptions initiated ~250,000 years before the Cretaceous-Paleogene boundary and that >1.1 million cubic kilometers of basalt erupted in ~750,000 Years.

Rapid short-term cooling following the Chicxulub impact at the Cretaceous–Paleogene boundary

It is demonstrated unambiguously that the impact at the Cretaceous–Paleogene boundary (K–Pg, ∼66 Mya) was followed by a so-called “impact winter,” which was the result of the injection of large amounts of dust and aerosols into the stratosphere and significantly reduced incoming solar radiation for decades.
