Schematic geodynamic model shows the operation of the Oligocene subduction zone below New Caledonia. (A) At ca. 29 Ma, the initiation of the subduction zone occurs in response to the opening of the North Loyalty and/ or South Fiji Basins. The free water carried by the subducting oceanic slab as well as fluids released from the breakdown of hydrous phases within it would metasomatize the overriding mantle wedge, lower its solidus, and result in partial melting of it, yielding La Conception lavas. (B) As the oceanic slab is subducted, it promotes more upward flow of the hot asthenosphere due to corner flow circulation in the mantle wedge. The upwelling asthenosphere would induce partial melting in the lower crust of New Caledonia at ca. 24 Ma, leading to formation of the felsic melts of the Saint Louis Massif and the Koum/ Borindi Massifs.
