...Dean M. Hoatson; Reid R. Keays Abstract The Munni Munni Complex (T Nd CHUR model age 2.85 Ga), located in the west Pilbara block of Western Australia, is one of the best preserved layered intrusions in Australia. Exposed over an area of 4 X 9 km, it is composed of a lower 1,850-m-thick ultramafic...

... such as the Stillwater and Munni Munni complexes. The mineralization at Legris Lake is best explained by the late-stage, immiscible separation of a sulfide melt from volatile-rich parental magmas and the subsequent minor redistribution of metals by deuteric fluids. The 7.3 km long by 3.5 km wide Legris Lake Complex...

... the redistribution of sulfur was due to late magmatic fluids dissolving S or the later metamorphic events. The association of PGE enrichment with magnetite layers in the Rio Jacaré intrusion contrasts with that of the Bushveld, Stillwater, Great Dyke, and Munni Munni Complexes. In these complexes PGE-enriched...

...) and of the Main Sulfide layer (offset portion) of the Munni Munni Complex (Western Australia), but the stratigraphic order of metal enrichment peaks is different (Pt → Pd → Au vs. Pd → Pt → Au). This suggests a reversal in the relative magnitudes of the partition coefficients D Pt and D Pd that was possibly...

... an unusual occurrence that embodies aspects of both stratiform PGE reefs and sulfide-rich Ni-Cu ores. A model is proposed for the origin of the ore-body which implies a continuum of orthomagmatic origins between both these styles of mineralization.
