Impacts of the Toba super-eruption on the pH of the Andaman Sea

Ana Alves, Matthieu Paulhac Buisson, Pascale Louvat, Claire Rollion‐Bard et autres

The Toba volcano super-eruption on the island of Sumatra occurred about 74,000 years ago[1], close to the transition between interglacial Marine Isotope Stage (MIS) 5 and glacial MIS 4. This eruption, called Youngest Toba Tuff (YTT), is currently described as the largest …

Carbon and Nitrogen Cycle Dynamic in Continental Late-Carboniferous to Early Permian Basins of Eastern Pangea (Northeastern Massif Central, France)

Mathilde Mercuzot, Christophe Thomazo, Johann Schnyder, Pierre Pellenard et autres

Late Carboniferous to early Permian organic-rich sedimentary successions of late-orogenic continental basins from the northeastern Massif Central (France) coincide with both the Variscan mountain dismantling and the acme of the long-lasting Late Paleozoic Ice Age. Here, we investigate the carbon and nitrogen …

Le rapport isotopique du bore dans l’océan, un marqueur géodynamique et climatique global : évaporites au Phanérozoïque et mesures miniaturisées de foraminifères à la transition interglaciaire-glaciaire à proximité du volcan Toba

Matthieu Paulhac Buisson

Face au changement climatique de l’Anthropocène, l’étude des paléoclimats et des perturbations associées du cycle du carbone au cours des temps géologiques s’est révélée fondamentale afin de comprendre les réactions du système Terre lors d’épisodes à forte teneur en CO2 atmosphérique. Depuis …

High precision MC-ICP-MS measurements of 11 B/ 10 B ratios from ng amounts of boron in carbonate samples using microsublimation and direct injection (μ-dDIHEN)

Matthieu Paulhac Buisson, Pascale Louvat, Caroline Thaler, Claire Rollion‐Bard

Boron extraction from the samples by microsublimation, use of a miniaturized direct injection system (μ-dDIHEN) and of 10 13 Ω amplifiers on the MC-ICP-MS allow precise δ 11 B measurements of very small and B-poor samples, such as marine carbonates.

Technical note: Single-shell δ 11 B analysis of Cibicidoides wuellerstorfi using femtosecond laser ablation MC-ICPMS and secondary ion mass spectrometry

Markus Raitzsch, Claire Rollion‐Bard, I. Horn, Grit Steinhoefel et autres

The boron isotopic composition ( δ 11 B) of benthic foraminifera provides a valuable tool to reconstruct past deep-water pH. As the abundance of monospecific species might be limited in sediments, microanalytical techniques can help to overcome this problem, but such studies …
