Journal ArticleDOI
Rare earth element systematics in hydrothermal fluids
TL;DR: In this paper, rare earth element concentrations have been measured in hydrothermal solutions from geothermal fields in Italy, Dominica, Valles Caldera, Salton Sea and the Mid-Atlantic Ridge.
Journal ArticleDOI
Rare-earth elements and uranium in high-temperature solutions from East Pacific Rise hydrothermal vent field (13 °N)
TL;DR: The mobility of rare-earth elements (REE) and U during hydrothermal alteration of the basalts at spreading centres has long been a matter of concern because of its bearing on the evolution and recycling of the oceanic crust.
Journal ArticleDOI
A major 2.1 Ga event of mafic magmatism in west Africa: An Early stage of crustal accretion
TL;DR: For example, in this article, three Sm-Nd isochrons on tholeiitic lavas were obtained at 2.229±0.042 Ga and initial eNd = 3.6±1.1 Ga.
Journal ArticleDOI
Crustal growth in West Africa at 2.1 Ga
TL;DR: The most precise zircon U-Pb and Sm-Nd data for the more widespread Birimian terranes (sensu stricto), from this study and from the literature, cluster between 2.12 and 2.07 Ga.
Journal ArticleDOI
The REE content of some hydrothermal fluids
Annie Michard,Francis Albarède +1 more
TL;DR: In this article, the authors determined that, in hydrothermal systems, REE are immobile at temperatures below 350°C and for water/rock ratios of <105.
