“…7b-d). Secondary sulfides might be produced by sulfidation reactions via metasomatic fluid infiltration (e.g., Fleet and Wu, 1995) or precipitation of Cu-Ni-rich sulfides from metasomatic sulfide melts (Alard et al, 2000;Lorand and Alard, 2001;Rehkämper et al, 1999a) or attainment of S-saturation in a silicate melt where fractional crystallization of silicates at low pressure induces sulfide precipitation (Harvey et al, 2015).…”

“…Screening olivine grains in crushed peridotite for chemical zoning derived from melt-rock interaction prior to digestion would be one such use of this technique. Another is obtaining 3D chemical information of olivine in-situ, providing context of such processes involved in the deposition, removal, and modification of accessory phases (Harvey et al, 2015).…”

Olivine is a key constituent in the silicate Earth; its composition and texture informs petrogenetic understanding of numerous rock types. Here we develop a quantitative and reproducible method to measure olivine composition in three dimensions without destructive analysis, meaning full textural context is maintained. The olivine solid solution between forsterite and fayalite was measured using a combination of three-dimensional (3D) X-ray imaging techniques, 2D back scattered electron imaging, and spot-analyses using wavelength dispersive electron probe microanalysis. The linear attenuation coefficient of natural crystals across a range of forsterite content from ~73-91 mol% were confirmed to scale linearly with composition using 53, 60 and 70 kV monochromatic beams at I12-JEEP beamline, Diamond Light Source utilising the helical fly-scan acquisition. A polychromatic X-ray source was used to scan the same crystals, which yielded image contrast equivalent to measuring the mol% of forsterite with an accuracy <1.0 %. X-ray tomography can now provide fully integrated textural and chemical analysis of natural samples containing olivine, which will support 3D and 3D+time petrologic modelling. The study has revealed >3 mm domains within a large crystal of San Carlos forsterite that vary by ~2 Fo mol%. This offers a solution to an outstanding question of inter-laboratory standardisation, and also demonstrates the utility of 3D, non-destructive, chemical measurement. To our knowledge, this study is the first to describe the application of XMT to quantitative chemical measurement across a mineral solid solution. Our approach may be expanded to calculate the chemistry of other mineral systems in 3D, depending upon the number, chemistry and density of end-members.

“…Type-2 sulfides may be derived by crystallization from a melt or liquid that was trapped during partial melting (Frick 1973; Mitchell and Keays 1981; Hamlyn and Keays 1986; Dromgoole and Pasteris 1987; Szabó and Bodnar 1995; Fig. 1) or introduced after melt depletion as a metasomatic melt or volatile-rich fluid (e.g., Alard et al 2002Alard et al , 2011Luguet et al 2008;Harvey et al 2011Harvey et al , 2015; Lorand and Luguet 2016, this volume). These sulfides are the most common BMS population in peridotites, whereas Type-1 sulfides are rare and generally restricted to peridotite xenoliths (e.g., Alard et al 2002).…”

ANALYTICAL METHODS AND PRACTICAL ASPECTS OF SAMPLE PREPARATION Over the last 15 years or so, two main methods have been developed for the analysis of Re-Os isotopes in BMS grains; (i) in situ laser ablation multi-collector inductively coupled plasma mass spectrometry (LA MC ICPMS) and (ii) sulfide extraction, chemical purification, and thermal ionization mass spectrometry (TIMS). Lead isotopes have also been measured using the TIMS technique, as well as by in situ secondary ion mass spectrometry (SIMS). There are distinct advantages and disadvantages associated with each analytical method, particularly with respect to sample preparation and interpretation of the information obtained. Early work on Pb, Re, Os, and other PGE concentrations in BMS grains was performed by in situ proton microprobe analysis coupled with a MC ICPMS (Bulanova et al. 1996; Guo et al. 1999). Due to limited availability and because detection limits were higher and standard reproducibility for this method was less precise, in situ determination of Re and PGE
