Geochemistry of the igneous rocks of the Belingwe Greenstone Belt: Alteration, contamination and petrogenesis

Autor: Nicholas Arndt, J.L. Orpen, Euan G. Nisbet, R. Renner, Anthony J. Martin, Mike J. Bickle, Reid R. Keays

The Belingwe Belt contains an andesitic suite, two suites of komatiites associated with voluminous tholeiites, and assorted intrusive igneous rocks. Some of the latter include remarkably fresh komatiite and basalt, containing little altered olivine a

Publikováno v: Ore Geology Reviews. 90:532-552

Four elongate, km-scale, mafic to ultramafic bodies (UMB) were identified within the Ordovician-Silurian Dido Batholith, north Queensland, and were assessed for Ni-Cu-PGE fertility. The UMB comprise layered cumulate sequences and represent open-syste

3D textural evidence for the formation of ultra-high tenor precious metal bearing sulphide microdroplets in offset reefs: An extreme example from the Platinova Reef, Skaergaard Intrusion, Greenland

Autor: Richard Prasser, Margaux Le Vaillant, Stephen Barnes, David A. Holwell, Louise Fisher, Reid R. Keays

Publikováno v: Lithos. :55-74

The Platinova Reef in the Skaergaard Intrusion, east Greenland, is an example of a type of layered-intrusion-hosted, precious metal-enriched, stratiform, disseminated sulphide deposit referred to as “offset reefs”. These typically show platinum-g

Controls on disseminated PGE–Cu–Ni sulfide mineralization within the Rietfontein deposit, Eastern Limb, Bushveld Complex, South Africa: Implications for the formation of contact-type magmatic sulfide deposits

Autor: Brendan Hardwick, Reid R. Keays, Simon M. Jowitt

Publikováno v: Ore Geology Reviews. 64:253-272

The Rietfontein platinum group element (PGE)–Cu–Ni sulfide deposit of the Eastern Limb of the Bushveld Complex hosts disseminated contact-style mineralization that is similar to other economic magmatic sulfide deposits in marginal settings within
