...Yves Lagabrielle; Alain Chauvet; Marc Ulrich; Stéphane Guillot Abstract The 300 km long allochthonous sheet of oceanic mantle forming the New Caledonia ophiolite displays three specific characters: 1) the ophiolite pile lacks concordant sheeted dykes and pillow basalt layers; 2) the ophiolite...

... with a composition close to NiAsS (probably gersdorffite). The geochemistry and mineralogy of the chromitite and the PGE mineralization show that the Ouen Island chromitites have a different origin than those found in the mantle and crust sequences of the New Caledonia ophiolite complex. The distribution, morphology...

.... Continued subduction of South Loyalty Basin crust led to the arrival at about 38 Ma of the 70–60 million years old western volcanic passive margin of the Norfolk Ridge at the trench, and west-directed emplacement of the New Caledonia ophiolite. Lowermost allochthons of this ophiolite are Maastrichtian...

...J. P. Paris; A. Colleau; M. Esterle ABSTRACT The economic development of New Caledonia is almost entirely dependent upon the exploitation of ore bodies emplaced within an overthrust ophiolite complex which covers about one-third of the island. The overthrust was an Eocene event and the ores...

...., Eliopoulos et al., 2012 ). The main ophiolite of New Caledonia (southwest Pacific Ocean), referred to as the peridotite nappe, has also undergone intense laterization since its emergence. This has led to supergene nickel ore formation, a process which implies a well-drained percolation system through...
