The isotopic diversity of oceanic island basalts (OIB) is usually attributed to the influence, in their sources, ancient material recycled into mantle, although nature, age, and quantities this remain controversial. unradiogenic Pb isotope signature enriched mantle I (EM I) source from, for example, Pitcairn or Walvis Ridge has been variously pelagic sediments, lower continental crust, subcontinental lithosphere. Our study helps resolve debate by showing that lavas contain sulfides whose...
Less than 25% of the volume juvenile continental crust preserved today is older 3 Ga, there are no known rocks approximately 4 and yet a number recent models growth suggest that at least 60-80% present had been generated by Ga. Such require large volumes pre-3 Ga were destroyed replaced younger since late Archaean. To address this issue, we evaluate influence on rock record changing rates generation destruction different times in Earth's history. We adopted box model approach numerical...
Abstract Most crustal rocks derive from preexisting crust, and so the composition of newly generated (juvenile) continental hence tectonic settings its formation, have remained difficult to determine, especially for first billion years Earth’s evolution. Modern primitive mantle–derived magmas distinct U/Pb ratios, depending on whether they are in intraplate (mean = 0.37) or subduction 0.10). The ratio can therefore be used as a proxy which juvenile crust is generated. This paper presents new...
A routine procedure is presented to analyse Pb isotopes in K-feldspar minerals and mineral inclusions zircon by LA-MC-ICP-MS, with a spot size down 10 μm.
A global supply shortage of a number key metals is forecast over the next few decades. There have been considerable advances in application situ isotope and trace element analyses a...
Dans les années 2010, Robert Darnton, spécialiste de l'histoire culturelle l'Europe moderne et des livres au xviiie siècle, Hélène Delavault, chanteuse lyrique cabaret, se sont associés autour d'un projet livre consacré à l'Affaire Quatorze (Paris, éditions Gallimard, 2014). En suivant l'enquête menée par la police parisienne qui a arrêté quatorze personnes pour déterminer provenance d'une ode portant atteinte l'honneur Louis XV sa maîtresse, Madame Pompadour, Darnton met en lumière le...
