TL;DR: In this paper, minor and trace element data obtained for ultrapure zircon fractions isolated from a variety of igneous rocks indicate that the presence of diagnostic geochemical signatures in igneous ZIRcon suites indicates that zircan can be used as a geochemical tracer and may be useful for identifying the geochemical nature of source regions in provenance studies of single detrital zirmin grains from sedimentary rocks or for deciphering basement rock compositions, if not exposed, from a geochemically study of xenocrystic Zircon grains.

TL;DR: In this paper, the authors present a set of partition coefficients for the lowest PGE contents investigated under reducing conditions and low Ni contents, except for the addition of a value of (4.4 ± 2.4) × 103 for Ru.

TL;DR: In this article, the authors show that anomalously high D(PGE-Au) values for the PGE-group elements (PGE)-Au partitioning of sulfide liquid and basaltic mixture can be minimized by degassing starting materials.

TL;DR: In this paper, the partitioning of Pd, Ir, and Pt between immiscible (Fe, Ni)-monosulfide liquid and basalt melt was investigated at 1300°C and at low pressure over the concentration range 40 to 20,000 ppm platinum-group element(s) (PGE) in the sulfide liquid, and at oxygen fugacities from the C-CO-CO2 to wustite-magnetite buffers.

TL;DR: In this paper, the sulfide liquid-silicate melt partition coefficients (D values) for the noble metals are (9 ± 7) × 10 4 for Pd, (1 ± 0.7) × 9.5) × 6.5 for Ir, ( 9 ± 6) × 5.3 for Pt, and (1 − 0.9) × 3.5 ) for Au.
