Nb-Ta fractionation in peraluminous granites: A marker of the magmatic-hydrothermal transition
In their late stages of evolution, peraluminous granitic melts exsolve large amounts of fluidswhich can modify the chemical composition of granitic whole-rock samples. The niobium/tantalum (Nb/Ta)Expand

Tectonic record, magmatic history and hydrothermal alteration in the Hercynian Guérande leucogranite, Armorican Massif, France
Abstract The Guerande peraluminous leucogranite was emplaced at the end of the Carboniferous in the southern part of the Armorican Massif. At the scale of the intrusion, this granite displaysExpand

The origin of water in the primitive Moon as revealed by the lunar highlands samples
The recent discoveries of hydrogen (H) bearing species on the lunar surface and in samples derived from the lunar interior have necessitated a paradigm shift in our understanding of the waterExpand

The abundance, distribution, and isotopic composition of Hydrogen in the Moon as revealed by basaltic lunar samples: Implications for the volatile inventory of the Moon
Abstract In this study we have measured the OH contents and D/H ratios in apatite grains in lunar basalts. These new data considerably expand the limited dataset published so far. The data presentedExpand

Lunar basalt chronology, mantle differentiation and implications for determining the age of the Moon
Despite more than 40 years of studying Apollo samples, the age and early evolution of the Moon remain contentious. Following the formation of the Moon in the aftermath of a giant impact, the resultExpand

Apatites in lunar KREEP basalts: The missing link to understanding the H isotope systematics of the Moon
Recent re-analyses of lunar samples have undoubtedly measured indigenous water, challenging the paradigm of a “dry” Moon, and arguing that some portions of the lunar interior are as wet as someExpand

Magmatic volatiles (H, C, N, F, S, Cl) in the lunar mantle, crust, and regolith: Abundances, distributions, processes, and reservoirs
Abstract Many studies exist on magmatic volatiles (H, C, N, F, S, Cl) in and on the Moon, within the last several years, that have cast into question the post-Apollo view of lunar formation, theExpand

Differentiation of peraluminous leucogranites “en route” to the surface
Abstract Leucogranites display petrological and geochemical heterogeneities that can be related to either primary processes in the source of melts or to secondary processes such as fractionalExpand

Petrology of igneous clasts in Northwest Africa 7034: Implications for the petrologic diversity of the martian crust
The martian meteorite Northwest Africa (NWA) 7034 was examined both petrographically and geochemically using several micro-beam techniques including electron probe microanalysis and secondary ionExpand

An asteroidal origin for water in the Moon
The Apollo-derived tenet of an anhydrous Moon has been contested following measurement of water in several lunar samples that require water to be present in the lunar interior. However, significantExpand
