▪ Abstract The Re-Os isotope sytem, based on the long-lived β− transition of 187Re to
187Os, has matured to wide use in cosmochemistry and high-temperature geochemistry …

The platinum-group element (PGE) systematics of continental mantle peridotites show large
variability, reflecting petrogenetic processing of the upper mantle during partial melting and …

Semiconductor nanocrystals were prepared for use as fluorescent probes in biological
staining and diagnostics. Compared with conventional fluorophores, the nanocrystals have …

Owing to advances in microanalytical techniques over the last 15 years, there is a growing
database on the volatile contents of subduction-related magmas as recorded in melt (glass) …

This paper presents definitions of concepts related to speciation of elements, more
particularly speciation analysis and chemical species. Fractionation is distinguished from …

The Re-Os isotopic systematics of spinel-and garnet-bearing mantle xenoliths from North
and Central America, Europe, southern Africa, Asia, and the Pacific region were determined …

Chromites forming giant orebodies in the southern part of the Early Palaeozoic ophiolite
sequence of the Kempirsai Massif (Kazakhstan, Urals) contain a large number of inclusions …

Spinel peridotites from a variety of island arcs have been utilised to calculate the redox state
of the mantle wedge above subduction zones. Oxygen fugacities (fO2 values) calculated …

We investigate the use of loess as a proxy for the concentration and isotopic composition of
highly siderophile elements, specifically Os, in the upper continental crust. The …

Previous studies of samples of subcontinental lithospheric mantle (SCLM) that underlay the
North China Craton (NCC) during the Paleozoic have documented the presence of thick …
