Ultramafic rocks outcrop over more than one third of New Caledonia's main island. Under tropical conditions, thick lateritic mantles with nickel concentrations developed on these rocks by geochemical weathering. Groundwater in ultramafic mined massifs represents a valuable resource, but also a severe constrain for mining engineering. Previous works describe several water tables in the various layers of the weathering mantle. From a hydrologic study of the Tiebaghi massif, the hydraulic continuity across the weathering layers down to the bedrock is proposed. specialized aquifer ultramafic rock mine regolith New Caledonia 068 062 337 16 1500-1508 2005 1631-0713 https://www.documentation.ird.fr/hor/fdi:010035842 10.1016/j.crte.2005.08.011 1631-0713 [F B010035842] https://www.documentation.ird.fr/hor/fdi:010035842 https://www.documentation.ird.fr/intranet/publi/2006/02/010035842.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2006-03-30 2017-08-23 fdi:010035842 fre
