Dead carbon in stalagmites: carbonate bedrock paleodissolution vs. ageing of soil organic matter. Implications for 13C variations in speleothems
Dominique Genty,Andy Baker,Marc Massault,Christopher J. Proctor,Mabs Gilmour,Edwige Pons-Branchu,Bruno Hamelin +6 more
TL;DR: In this article, a 14C accelerator mass spectrometric analysis was performed for three Holocene stalagmites from the Uamh-an-Tartair cave (Sutherland, Scotland) in order to estimate the past dead carbon proportion (dcp).
Journal ArticleDOI
Rapid and Accurate U-Th Dating of Ancient Carbonates using Inductively Coupled Plasma-Quadrupole Mass Spectrometry
Eric Douville,Eline Sallé,Norbert Frank,Markus Hermann Eisele,Edwige Pons-Branchu,Sophie Ayrault +5 more
TL;DR: ICP-QMS has been used to date deep-water corals and stalagmites with high precision of 3.4 and 1.1%, respectively, this paper, using a simplified chemical separation technique for uranium and thorium using UTEVA resin.
Journal ArticleDOI
Speleothem record of the last 180 ka in Villars cave (SW France): Investigation of a large δ18O shift between MIS6 and MIS5
K. Wainer,K. Wainer,Dominique Genty,Dominique Blamart,M. Daëron,Miryam Bar-Matthews,Hubert B. Vonhof,Yuri Dublyansky,Edwige Pons-Branchu,L. E. Thomas,P. van Calsteren,Yves Quinif,Nicolas Caillon +12 more
TL;DR: The Vil-car-1 flowstone core from Villars cave (SW France) provides one of the first European speleothem records extending back to 180 ka, based on UeTh TIMS and MC-ICP-MS measurements as mentioned in this paper.
Journal ArticleDOI
A geochemical perspective on Parisian urban history based on U–Th dating, laminae counting and yttrium and REE concentrations of recent carbonates in underground aqueducts
Edwige Pons-Branchu,Eric Douville,Matthieu Roy-Barman,Emmanuel Dumont,Philippe Branchu,François Thil,Norbert Frank,Louise Bordier,Wolfgang Borst +8 more
TL;DR: In this article, two laminated carbonate deposits from the wall of an underground aqueduct, built between the 13 and 15 th century, in Paris, France, were studied to provide historical information about nearby human occupation and urban development.
Journal ArticleDOI
Improved method for radium extraction from environmental samples and its analysis by thermal ionization mass spectrometry
TL;DR: In this paper, an efficient procedure for the chemical separation of radium-226 from environmental samples and its measurement by thermal ionization mass spectrometry was developed, which does not require a preliminary evaporation stage, thereby eliminating problems due to the precipitation of large quantities of salts and permits the analysis of femtogram levels of 226Ra.
