Fig. 2 (a) Schematic cross section of the Koniambo klippe showing the faulted peridotites capped by Ni-laterites. Note that walls of thrusting and normal faults are extensively serpentinized (black) in the peridotites (dark green). Normal faults close to the surface are also deeply mineralized

... soils. Since Glasser (1904) , the origin of the veins is supposed supergene, possibly linked to the laterization process. The Koniambo massif is one of the klippes of the peridotite nappe located along the west coast ( Fig. 1A ). Recently, Koniambo Nickel SAS initiated a large industrial site...

..., 1973 ; Chevillotte et al., 2006 ). Plateaus, which are morphologically inverted lowlands, are mainly exposed in the northernmost klippes (Bélep, Tiébaghi, Poum) ( Latham, 1986 ). Partly dissected plateaus have stepped planation surfaces and incised glacis, e.g., Koniambo and Boulinda massifs...

... to shear. Interestingly, an 80% porosity is indeed experimentally observed as a maximum porosity in freely drained regoliths formed on ultramafic rocks (Koniambo klippe, New Caledonia) and similar mining circumstances. Small changes of microstructure will modify this prediction but, for most applications...

... klippes, identified by Raman spectroscopy, HR-TEM and XRD (L2, lizardite-1 T ; C3, chrysotile-2 M ; A2, antigorite) ( Fritsch et al. , 2016 ). Lizardite is commonly dominant in the upper part of the klippes (or ophiolite nappe) and observed as very thin millimetric meshes or thicker crosscutting black...

... section. According to Ulrich et al. [2010] , a large proportion of the ophiolite mantle of New Caledonia is composed of highly depleted harzburgites (± dunites) with characteristic U-shaped bulk-rock rare-earth element (REE) patterns, as shown by analyses performed in Koniambo and Thiébagi massifs...
