LA GALLEGA MINE (OJÉN)

Ni-Co arsenides veins, intergrowth with chromitite bands (bearing Ni-chromite). Mineralization is included in cordierite dykes. These cordierite dykes are embedded in highly serpentinized peridotites (spinel type Lherzolites).

Source: Phase I Orthomagmatic (chromite-pyroxene stage),
Phase II of magmatic inmiscibility involving liquid oxide-arsenide (chromite-niccolite). High temperature hydrothermal veins phases containing Fe-Co sulphides and Ni-Co arsenides.
