Stephen J. Barnes, Auteur ; Marco L. Fiorentini, Auteur |Komatiites are found in most Archean granite-greenstone terranes, but sulfide Ni mineralization associated with these rocks has a very biased distribution. The global endowment of sulfides Ni in Archean komatiites is overwhelmingly dominated by [...]

Geoffrey J. Heggie, Auteur ; Marco L. Fiorentini, Auteur ; Stephen J. Barnes, Auteur |Komatiites occur in many Archean greenstone belts and host significant Ni sulfide ore deposits. Establishing the stratigraphy and the control that stratigraphy has on the emplacement and morphology of ultramafic magmatism is crucial in understan[...]

Geoffrey J. Heggie, Auteur ; Marco L. Fiorentini, Auteur ; Stephen J. Barnes, Auteur |The Maggie Hays Ni-Cu sulfide deposit, located in the ~2.9 Ga Lake Johnston greenstone belt of Western Australia, is hosted in a peridotitic to dunitic subvolcanic feeder that cuts felsic volcanic rocks and sedimentary units. Ore formation at[...]

Marco L. Fiorentini, Auteur ; Andrey Bekker, Auteur ; Olivier Rouxel, Auteur |We report here high-precision multiple sulfur and iron isotope compositions for a series of mineralized samples from Ni-Cu-(PGE) sulfide deposits in the Archean Tati greenstone belt and the Phikwe Complex of eastern Botswana. Mineralized samples[...]

Marco L. Fiorentini, Auteur ; Stephen J. Barnes, Auteur ; C. Michael Lesher, Auteur |Platinum-group elements (PGE) are strongly chalcophile and are therefore potentially sensitive indicators of processes involving segregation and accumulation of sulfide melts from silicate magmas. Over 500 new high-precision PGE data for komatii[...]
