Journal ArticleDOI
Chromium availability in ultramafic soils from New Caledonia.
TL;DR: Cr concentrations were larger in well aerated colluvial soils, where high levels of Mn-oxides are able to oxidize Cr(III) to Cr(VI), than in piedmont soil where the Mn-oxide content is lower, or in alluvial soil from the lowlands, where waterlogging occurs.
Journal ArticleDOI
Sources of trace metals in Ferralsols in New Caledonia
Thierry Becquer,Cécile Quantin,S. Rotte-Capet,Jaafar Ghanbaja,Christian Mustin,Adrien Herbillon +5 more
TL;DR: In this paper, the location of the metals present in three samples from a toposequence of Ferralsols was studied by combining selective dissolutions (CaCl2, Cu(NO3)(2), hydroxylamine, dithionite-citrate-bicarbonate), examinations with a transmission electron microscope (TEM) equipped with an EDAX device, and X-ray diffraction and infrared spectroscopy.
Journal ArticleDOI
The origin and timing of fluvial activity at Eberswalde crater, Mars
N. Mangold,Edwin S. Kite,Maarten G. Kleinhans,Horton E. Newsom,Veronique Ansan,Ernst Hauber,E. R. Kraal,Cécile Quantin,K. L. Tanaka +8 more
TL;DR: The Eberswalde basin has been interpreted as strong evidence for sustained liquid water on early Mars with a paleolake formed during the Noachian period (>3.7 Gy) as mentioned in this paper.
Journal ArticleDOI
PAH dissipation in a contaminated river sediment under oxic and anoxic conditions.
TL;DR: It is concluded that natural attenuation of PAHs in polluted river sediments under anaerobic conditions is exceedingly slow, and dredging and biodegradation on land under aerobic conditions would be required to safely remediate and restore polluted sites.
Journal ArticleDOI
Oxide weathering and trace metal release by bacterial reduction in a New Caledonia Ferralsol
TL;DR: In this paper, anaerobic Fe- and Mn-reducing bacterial activity was responsible for Fe-and Mn-oxide solubilization by either respiration or fermentation, while Mnoxide appeared as the major reducible phase and metal source rather than goethite.
