...Bocheng Ma; Reid R. Keays Abstract The thick laterite developed over platinum group element (PGE)-bearing ultramafic rocks of the Owendale Alaskan-Uralian Complex in New South Wales, Australia, provides an ideal environment in which to address the question of whether Pt-Fe nuggets are formed during...

... and consists of small dunite bodies rimmed with clinopyroxenite, gabbro, diorite, and monzodiorite. In contrast with PGE mineralization in other Alaskan-type complexes that is hosted in chromitites of the dunite core, the highest PGE concentrations at Owendale occur in the clinopyroxenite unit. The Kelvin...

... complexes. Such complexes intruded Mesozoic sedimentary rocks. They form the primary source of PGM. The PGM placer nuggets vary considerably in size (0.1–9 mm), shape, and degree of abrasion, indicating a long history of placer-forming processes. Some of the nuggets are covered by shells of detrital...
