...; Dundonald Beach South, Canada). Platinum-group elements (PGE) have shown to have a strong affinity for arsenide melts, but little is known about their partitioning behavior between arsenide and sulfide melts. In this study, we experimentally determine the partition coefficients of PGE (Pt, Pd, Ir, Ru...

... samples and explore the influence of capsule materials and oxygen fugacity ( f O 2 ) on the loss behavior of elements. The starting material is a synthesized basaltic glass consisting of 8 major elements and 37 trace elements. The sample capsules included platinum (Pt), graphite-lined Pt, and rhenium...

Khanin Abstract The Itchayvayamsky Ural-Alaskan-type massif is located in the northernmost part of the Koryak-Kamchatka Platinum Belt (Russia) and is surrounded by two rivers (Kamenistaya and Itchayvayam) that both...

..., and toxicity data for the platinum-group elements (PGEs) is now gaining increased attention. It has been estimated that, despite the low annual Pt emission of 0.5–1.4 tons y −1 , the levels of PGEs in ice cores in Greenland are 40–120 times higher than in ice from 7,000 years ago ( Barbante et al. 2001...
