Extremely voluminous magmatic systems known as large igneous provinces (LIPs)
punctuate Earth's history, and the gases they release plausibly link large-scale geodynamic …

Natural Fe-bearing ochres ranging in color from yellow to deep red and brown abound on
earth's crust. Quite often, ochres can be used for pigmenting purposes upon little or no …

Temporal correlation between some continental flood basalt eruptions and mass extinctions
has been proposed to indicate causality, with eruptive volatile release driving environmental …

The cause of the end-Cretaceous mass extinction is vigorously debated, owing to the
occurrence of a very large bolide impact and flood basalt volcanism near the boundary …

Weathering profiles developed on basalt substrate contain information relevant to climate,
atmospheric composition and evolution, nutrient release into the hydrosphere, and …

Bolide impact and flood volcanism compete as leading candidates for the cause of terminal-
Cretaceous mass extinctions. High-precision 40Ar/39Ar data indicate that these two …

Despite decades of study, the structures adopted to accommodate an excess proton in water
and the mechanism by which they interconvert remain elusive. We used ultrafast two …

The Chicxulub asteroid impact (Mexico) and the eruption of the massive Deccan volcanic
province (India) are two proposed causes of the end-Cretaceous mass extinction, which …

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

High-precision high field strength element (HFSE: Zr, Hf, Nb, Ta, Th, U, W, Mo), Y/Ho, and
Nd isotope chemostratigraphy of two contrasting Deccan Traps weathering profiles–an …
