The major magmatic volatile components—H2O, CO2, S, Cl, and F—play an important role
in the formation, evolution, and eruption of magma. Knowledge of magmatic concentrations …

BACKGROUND Rocks from the Earth's mantle occur in a wide range of geologic settings (1)
as peridotite massifs, now referred to as orogenic peridotites;(2) as spinel-(rarely garnet) …

In 1794, the German physicist EFF Chladni published a small book in which he proposed
the extraterrestrial origin of meteorites. The response was skepticism and disbelief. In the …

The association of large Au–Cu–Ag ore deposits with convergent margins is commonly
attributed to the higher content of chalcophile elements in the parental magmas generated at …

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

Since the first application of the 187Re–187Os isotope system to determine the timing of
melt extraction from peridotites twenty years ago, a plethora of studies have demonstrated its …

The concentrations of platinum-group elements (PGE), Co, Re, Au and Ag have been
determined in the base-metal sulphide (BMS) of a section of the Merensky Reef. In addition …

We report on improvements to the sulfur extraction method out of silicate glasses by the use
of HF+ CrCl2 solution for the precise determination of S multi-isotope compositions. This …

Addition of crustal sulfur to the Jinchuan magma or oxidation of the magma associated with
carbonate assimilation has been considered to be the main cause of sulfide saturation in the …

In this study, we applied high-precision in situ Fe and Mg isotope analyses by femtosecond
laser ablation (fs-LA) MC-ICP-MS on chemically zoned olivine xeno-and phenocrysts from …
