The Nebo-Babel deposit is a layered, basic, tube-like body intruding felsic granulite facies country rock in the west Musgrave Block, Western Australia. Nebo-Babel is the largest nickel sulphide discovery since Voisey’s Bay, Canada. The deposit is the faulted offset of a tube-like intrusion, which trends SW-NE for about 5 km and has a cross-section of 1 x 0.5 km. The principal rock type is gabbronorite with variable proportions of plagioclase, ortho– and clinopyroxene, minor olivine, oxides and apatite. Mineralised zones are confined to the top and upper parts of the intrusion and comprise disseminated magmatic sulphides and massive sulphide lenses. Field, mineralogical and geochemical data suggest that the marginal units crystallised first under open system conditions. After magma supply ceased, inner units which exhibit ‘normal’ vertical fractionation trends, crystallised under closed system conditions. This PhD research concentrates on providing better understanding of the geology, mineralogy, geochemistry and geochronology of the Nebo-Babel nickel sulphide deposit. Ultimately, it should better constrain the key requirements for the formation of nickel sulphide deposits associated with basaltic magmas of the Giles Complex.
