Komatiites erupted billions of years ago as pulsating streams of white-hot lava. Their unusual chemical compositions and exceptionally high formation temperatures produced highly fluid lava that crystallized as spectacular layered flows. Investigation of the extreme conditions in which komatiites formed provides important evidence about the …

The Perseverance Ni-sulphide deposit and nearby Rockys Reward, Harmony, and Venus deposits are hosted within komatiite sequences that extend for approximately 15 km along the eastern margin of the Archean Agnew-Wiluna greenstone belt (AWB, Fig. 1 a). The economic significance of these deposits has attracted numerous studies over the …
Details
Most komatiite-associated magmatic Ni–Cu–(PGE) sulfide deposits formed from sulfide-undersaturated magmas and are interpreted to have formed in dynamic lava channels or magma conduits by incorporation of crustal sulfur. They commonly exhibit geochemical and isotopic evidence of crustal contamination and chalcophile element …

Platinum and palladium are typically strongly correlated in S-poor komatiites, at a ratio close to 1:1 (Fig. 1).The correlation persists through low-grade disseminated ores, although the ratio of Pd/Pt increases to 2:1 for poorly understood reasons discussed by Barnes et al. in press-a.Within massive and semi-massive sulfide ores, however, the …

Komatiites are fascinating volcanic rocks. They are among the most ancient lavas of the Earth following the 3.8 Ga pillow basalts at Isua and they represent some of the oldest ultramafic magmatic rocks preserved in the Earth's crust at 3.5 Ga. This fact, linked to their particular features (high magnesium content, high melting temperatures, low …

Komatiites are distinguished as ultramafic volcanic rocks containing spinifex olivine textures with MgO contents >18 wt% (Fig. 1). The maximum MgO content of komatiites is probably 25–30 wt% MgO, but this is a controversial issue, because all komatiites have been chemically modified by metamorphic processes. ... Magmas and …
