Highly anomalous platinum-group element (PGE) concentrations in the podiform chromitites at the Cliff and Harold's Grave localities in the Shetland ophiolite complex have been well documented previously. The focus of this study is alluvial platinum-group minerals (PGM) located in small streams that drain from the PGE-rich chromitites.
Barnes et al. (1985) divided the PGE into two groups: Os, Ir, Ru (Ir-PGE) and Rh, Pt, Pd (Pd-PGE) based on the fact that Os, Ir, Ru behave as compatible elements during partial …
Concentration patterns of platinum-group elements are typical for ophiolitic chromitite poor in sulfides, with predominance of the IPGE, variable Rh, and low Pt and Pd. ...

The Longzhoushan and Ertan basalts in the Pan-Xi area were generated by relatively low degrees of partial melting (< 7%), during which Ir, Ru, and Rh are compatible while Pt and Pd are incompatible. Most of these samples have high PGE concentrations and much higher Pd/Ir and Cu/Pd ratios than those of primitive mantle. A small amount of …

Abstract. No definite date can be ascribed to the discovery of platinum; rather it became gradually known to the Western World as a distinct metal of unique properties over a period of two centuries, between 1500 and 1700. The first source to be exploited was the placer deposits in New Granada (now Colombia) where it was initially regarded as a ...
