Characterization of pentlandite-bearing quartz veins of Kambalda, Western Australia
The Kambalda Dome of the Yilgarn Craton is located in Western Australia and has been historically mined for Ni after the discovery of magmatic sulfide orebodies in 1966. The Ni orebodies consist of komatiite-associated magmatic sulfide deposits which have experienced deformation, metamorphism and …

Metamorphic and crustal evolution of Australian-Antarctic Proterozoic margins
… to represent a detached fragment of the Archean Yilgarn Craton that underwent (para)autochthonous crustal reworking during the Paleo–Mesoproterozoic. The tectonic evolution of the Bunger Hills is therefore strongly allied with the west Albany–Fraser Orogen, southwest Australia (also west MAFWO). …

Paleomagnetic and Rock Magnetic Analysis of Upper Cretaceous Synorogenic Conglomerates From the Cordilleran Foreland Basin, Utah; Middle Triassic Moenkopi Formation From the Petrified Forest National Park, Arizona; and Pseudotachylytes From the Albany-Fraser Orogenic Belt, Southwest Australia
… Albany Fraser orogenic belt of the Yilgarn Craton. Analysis showed that the PST and HR samples contain contrasting rock-magnetic properties and magnetic fabrics. Microscopic observations of pseudotachylyte rocks show grainsize reduction, enhancement of specific mineral phases (e.g., …

Compositions, logratios and geostatistics: An application to iron ore
Common implementations of geostatistical methods, kriging and simulation, ignore the fact that geochemical data are usually reported in weight percent, sum to a constant, and are thus compositional in nature. The constant sum implies that rescaling has occurred and this can be shown to produce …
