In November 2011 and July 2012 were conducted geophysical prospections in the southern part of New Caledonia. Both electrical tomography (ERT) and Magnetic Resonance Sounding (MRS) were performed to obtain a better understanding of the water storage and circulation. The geological context is the weathering profile of peridotite rock (Maurizot and Vendé-Leclerc, 2009). We present a review of the various ERT and MRS responses observed in this context.
