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… Expand
Widespread silicic and alkaline magmatism synchronous with the Deccan Traps flood basalts, India
Abstract Deccan Traps (DT) volcanism and the Chicxulub bolide impact have been suggested as potential triggers of the Cretaceous–Paleogene boundary (KPB) mass extinction. Recently publishedExpand
U-Pb zircon age constraints on the earliest eruptions of the Deccan Large Igneous Province, Malwa Plateau, India
Abstract Climate instability driven by emission of volatiles during emplacement of large igneous provinces (LIPs) is frequently invoked as a potential cause of mass extinctions. However, documentingExpand
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.

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.Expand
Contemporary researches and issues related to the Deccan volcanism
In the past few decades, late Cretaceous Deccan volcanism witnessed extensive researches, focused on nature, variety and genesis of magma, emplacement span [entail Cretaceous /Palaeogene (K/Pg)Expand
Influence of the Latest Maastrichtian Warming Event on planktic foraminiferal assemblages and ocean carbonate saturation at Caravaca, Spain
ABSTRACT A global warming episode in the Late Cretaceous, the Latest Maastrichtian Warming Event (LMWE), has been commonly linked to both the onset of massive Deccan Trap volcanism and the start of aExpand
Stable climate in India during Deccan volcanism suggests limited influence on K–Pg extinction
Abstract Large igneous provinces (LIPs) have been temporally correlated to mass extinctions throughout the Phanerozoic, including the emplacement of the Deccan Volcanic Province (DVP; 66.3–65.6 Ma)Expand
Asteroid impact, not volcanism, caused the end-Cretaceous dinosaur extinction
The results support the asteroid impact as the main driver of the non-avian dinosaur extinction, by contrast, induced warming from volcanism mitigated the most extreme effects of asteroid impact, potentially reducing the extinction severity. Expand
Stratigraphy and correlations in Deccan Volcanic Province, India: Quo vadis?
The Deccan Volcanic Province (DVP) is significant for its eruption close to Cretaceous–Paleogene (K-Pg) boundary. Chemostratigraphy established in its western parts is the foundation of postulatedExpand
Apatite (U-Th)/He thermochronometric constraints on the northern extent of the Deccan large igneous province
Abstract The volcanic emplacement and subsequent weathering of the Deccan Traps of India is believed to have had a significant influence in driving global climatic shifts from the Late Cretaceous andExpand


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. Expand
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. Expand
Triggering of the largest Deccan eruptions by the Chicxulub impact
New constraints on the timing of the Cretaceous-Paleogene mass extinction and the Chicxulub impact, together with a particularly voluminous and apparently brief eruptive pulse toward the end of theExpand
Time Scales of Critical Events Around the Cretaceous-Paleogene Boundary
Radiometric dating establishes the mass extinction that killed the dinosaurs as synchronous with a large asteroid impact between the Cretaceous-Paleogene boundary and associated mass extinctions with the Chicxulub bolide impact to within 32,000 years. Expand
Pre-Deccan and Deccan Magmatism in Kutch, India: Implications of New 40 Ar/ 39 Ar Ages of Intrusions
The Deccan Traps are of global interest for their possible links to Cretaceous-Tertiary (K-T) mass extinction event and global climate change. Radiometric dating of Deccan Trap lavas and intrusionsExpand
Main Deccan volcanism phase ends near the K-T boundary: Evidence from the Krishna-Godavari Basin, SE India
Abstract Recent studies indicate that the bulk (80%) of the Deccan trap eruptions occurred over less than 0.8 m.y. in magnetic polarity C29r spanning the Cretaceous–Tertiary (K–T) boundary.Expand
Determination of rapid Deccan eruptions across the Cretaceous‐Tertiary boundary using paleomagnetic secular variation: Results from a 1200‐m‐thick section in the Mahabaleshwar escarpment
[1] Flow-by-flow reanalysis of paleomagnetic directions in two sections of the Mahabaleshwar escarpment, coupled with analysis of intertrappean alteration levels shows that volcanism spanned a muchExpand
A new high-resolution chronology for the late Maastrichtian warming event: Establishing robust temporal links with the onset of Deccan volcanism
The late Maastrichtian warming event was defined by a global temperature increase of ∼2.5–5 °C that occurred ∼150–300 k.y. before the Cretaceous-Paleogene (K-Pg) mass extinction. This transientExpand
Extinction patterns, δ18 O trends, and magnetostratigraphy from a southern high-latitude Cretaceous–Paleogene section: Links with Deccan volcanism
Although abundant evidence now exists for a massive bolide impact coincident with the Cretaceous–Paleogene (K–Pg) mass extinction event (~ 65.5 Ma), the relative importance of this impact as anExpand
Early and Late Alkali Igneous Pulses and a High-3He Plume Origin for the Deccan Flood Basalts
Rocks from the older complexes show a 3He/4He ratio of 14.0 times the air ratio, an initial 87Sr/86Sr ratio of 0.70483, and other geochemical characteristics similar to ocean island basalts; the later alkalic pulse shows isotopic evidence of crustal contamination. Expand
