... beneath the South Pacific, probably related to upwelling of a large plume ( Fukao, 1992 ). Although the geochemistry of platinum-group elements (PGEs) in OIBs has the potential to provide key information on deep-mantle processes, few new data on PGE abundances in OIBs have appeared since the work...

...John F. W. Bowles; Andrew P. Gize; Alistair Cowden Abstract Suggestions that platinum-group minerals (PGM) may develop in supergene environments have created controversy. The opposing view is that they act solely as resistate phases during weathering. There is, however, significant evidence...

... of Pt and Pd as aqueous Cl complexes, are consistent with the formation of the J-M reef by exsolution of Cl- and volatile-rich fluids from footwall intercumulus liquids which leached and transported ore components (both the PGE and S) upward to the level of the reef.Using published whole-rock platinum...

...C. Li; Anthony J. Naldrett; C. J. A. Coats; P. Johannessen Abstract Recent study of the platinum-group elements (PGE) in the Strathcona Ni-Cu sulfide deposit has shown that their distribution is zoned. Pt, Pd, Au, and Cu increase progressively, from the Hanging-wall ore zone through the Main zone...

...Roland K. W. Merkle Abstract The platinum-group minerals in a drill core taken through the middle group of chromitite layers in the Critical Zone at Marikana in the western Bushveld Complex were found to consist mainly of laurite as inclusions in chromite grains. The platinum-group minerals...
