Gueguen, Bleuenn / Rouxel, Olivier / Rouget, Marie-laure / Bollinger, Claire / Ponzevera, Emmanuel / Germain, Yoan / Fouquet, Yves - 2016Ferromanganese (Fe-Mn) crusts are potential archive of the Ni isotope composition of seawater through time. In this study we aim at (1) understanding Ni isotope fractionation mechanisms and metal enrichment processes in Fe-Mn deposits, (2) addressing global vs. local control of Ni isotope...Contributeur (s):

Dekov, Vesselin M. / Rouxel, Olivier / Kouzmanov, Kalin / Bindi, Luca / Asael, Dan / Fouquet, Yves / Etoubleau, Joel / Burgaud, Gaetan / Walle, Markus - 2016Active and inactive hydrothermal chimneys composed almost entirely of enargite and luzonite, rare minerals in seafloor hydrothermal deposits, were found at the summits of two submarine volcanoes, North Su and Kaia Natai, in the Manus Back-Arc Basin. Detailed mineralogical and geochemical studies...Contributeur (s):

Auzende, Jean-marie / Ballu, Valerie / Batiza, R / Bideau, Daniel / Cormier, Mh / Fouquet, Yves / Geistdoerfer, Patrick / Lagabrielle, Yves / Sinton, J / Spadea, P - 1994The submersible-study of four segments of the East Pacific Rise between 17 degrees and 18 degrees 40'S, where the spreading rate is greater than 150 mm/a, allows us to confirm the variability of the accretion processes. The segment between 17 degrees and 17 degrees 30'S shows an intense...Contributeur (s):

Geistdoerfer, P / Auzende, Jean-marie / Batiza, R / Bideau, Daniel / Cormier, Mh / Fouquet, Yves / Lagabrielle, Yves / Sinton, J / Spadea, P - 199570 hydrothermal sites were observed during the 23 dives of the French submersible Nautile (''Naudur'' cruise, December 1993), at 17-degrees-19-degrees-S on the East Pacific Rise. Large vent-animal communities are present around these sites. The zoological composition of these...Contributeur (s):

Bougault, Henri / Charlou, Jean-luc / Donval, Jean-pierre / Fouquet, Yves / Pelle, H - 1990Responsible for large exchanges between the Ocean and the Lithosphere, oceanic hydrothermalism covers wide scientific domains, from the ocean chemistry to metallogeny. The exploration covers all scales, from the hydrothermal site to the Mid-oceanic ridge system. Modern bathymetry and imagery are...Contributeur (s):

Dives were conducted between 17 degrees 5 and 18 degrees 40'5 on four segments showing marked contrast in morphology, volcanic, tectonic and hydrothermal activity. At 17 degrees 10'5, 17 degrees 25'5 and 18...Contributeur (s):

Etoubleau, Joel / Bohn, Marcel / Fouquet, Yves / Cambon, Pierre / Le Suave, Raymond - 2000A range of X-ray analytical techniques contributes particularly well to the mineralogical and geochemical characterisations of cobalt-rich iron and manganese oxides crusts. X-ray diffraction is used to identify the weak crystallinity of the material. Bulk geochemical characterisation of the crusts...Contributeur (s):

Dekov, V. M. / Lalonde, Stefan / Kamenov, G. D. / Bayon, Germain / Shanks, W. C., Iii / Fortin, D. / Fouquet, Yves / Moscati, R. J. - 2015An inactive vent field comprised of dead chimneys was discovered on the ultrafast East Pacific Rise (EPR) at 18°S during the research campaign NAUDUR with the R/V Le Nadir in December 1993. One of these chimneys was sampled, studied and found to be largely composed of silica-mineralized bacterial-...Contributeur (s):

Pierre, Catherine / Rouchy, Jean-marie / Blanc-valleron, Marie-madeleine / Etoubleau, Joel / Fouquet, Yves - 2015Dolomite nodules are widespread within the Tortonian marls of Fortuna and Lorca basins in southern Spain. They occur as large bodies of various forms (round, ovoid, tabular) that are parallel or secant relative to the stratification. They are massive and present sometimes internal conduits that are...Contributeur (s):
