Ferritchromite and chromian-chlorite formation in mélange-hosted Kalkan chromitite (Southern Urals, Russia)
Abstract Spinel is often used as a magmatic indicator of crystallization processes, without considering the effects of metamorphic alteration on spinel geochemical features. Serpentinized mélanges inExpand
Synchrotron X-ray powder diffraction study of natural P2 /n-omphacites at high-pressure conditions
Abstract Synchrotron X-ray powder diffraction experiments at high pressure conditions (0.0001–13 GPa) were performed at ESRF (Grenoble-F), on the beamline ID9, to investigate the bulk elasticExpand
Pressure–volume–temperature equation of state of andradite and grossular, by high-pressure and -temperature powder diffraction
Abstract The thermoelastic parameters of natural andradite and grossular have been investigated by high-pressure and -temperature synchrotron X-ray powder diffraction, at ESRF, on the ID30 beamline.Expand
A single-crystal neutron and X-ray diffraction study of elbaite
The crystal chemistry and crystal structure of gem-quality elbaite from the Pederneira mine, São José da Safira, Minas Gerais, Brazil, were investigated by electron microprobe analysis in wavelengthExpand
Equation of state, structural behaviour and phase diagram of synthetic MgFe2O4, as a function of pressure and temperature
The behaviour of synthetic Mg-ferrite (MgFe2O4) has been investigated at high pressure (in situ high-pressure synchrotron radiation powder diffraction at ESRF) and at high temperature (in situExpand

Monazite specimens from various localities in the Alps have been examined by electon microprobe and by singlecrystal X-ray diffraction. With the exception of Sm, which is higher in general inExpand
Chemical analyses of Bronze Age glasses from Frattesina di Rovigo, Northern Italy
Abstract Within the frame of a project aimed to systematically characterize Bronze Age glasses in Northern Italy, a few glasses from Frattesina (Rovigo, Italy) were chemically analyzed byExpand
Micro-Raman spectroscopy as a routine tool for garnet analysis.
A rapid system to obtain molar compositions of minerals belonging to the garnet group by means of Raman spectroscopy is illustrated here. A series of standard garnets, whose composition wasExpand
