Résumé

5. Rare Earth Elements proxy of elemental mobility Conclusion The oxidation fronts underline preferential pathways for the ground water, localized along the CDBs (fig. 3). CDBs seem to constitute a trap where the oxides, contained in the fluid, are accumulated. Fluid circulations have print specific rare earth element (REE) pattern in sandstone host rocks, clays and oxides (fig.5). They particularly print heavy REE enrichment patterns, the light REE remain in fluids and are carried downstream. Further analysis have to be performed on groundwater to verify this hypothesis. BDs are both pipes and barriers to the fluid circulations along the fault zone.
