M Wilson - 1989 - Springer
A map of the ocean basins (Fig. 5.1) shows that their most conspicuous topographic feature
is the system of mid-oceanic ridges, the crests of which rise on average 1000-3000 m above …

Factors controlling chemistry of magmatic spinel: an empirical study of associated olivine, Cr-spinel and melt inclusions from primitive rocks
Compositions of∼ 2500 spinel–olivine pairs and 400 melt inclusion–spinel pairs have been
analysed from 36 igneous suites from oceanic, arc and intraplate tectonic settings. Our data …

Chemistry of chromian spinel in volcanic rocks as a potential guide to magma chemistry
S Arai - Mineralogical magazine, 1992 - cambridge.org
Chromian spinel in volcanic rocks is a potential discriminant for magma chemistry. The TiO2
content of spinel, compared at similar Fe3+/(Cr+ Al+ Fe3+) ratios, can distinguish island arc …

Experimentally determined partitioning of high field strength-and selected transition elements between spinel and basaltic melt
Partition coefficients for the elements Ta, Nb, Hf, Zr, Sc, V, Ga, Zn and Co have been
determined by laser ablation ICP-MS and/or electron microprobe between spinel and melt …

Zinc isotope fractionation between Cr-spinel and olivine and its implications for chromite crystallization during magma differentiation
We report the first zinc isotope data (expressed as δ 66 Zn relative to the JMC-Lyon
standard) for chromian spinels (Cr-spinels) and coexisting olivines in oceanic peridotites. All …

A novel hypothesis for origin of massive chromitites in the Bushveld Igneous Complex
The origin of chromitites in the Bushveld Complex has been attributed to two principal
mechanisms:(1) gravity-controlled settling of chromite onto the chamber floor from magma …
