The crystal chemistry of clinopyroxene, orthopyroxene and olivine from a crushed fragment of the H5 Zaoyang chondrite has been investigated by X-ray structure refinement and detailed microprobe analysis. The meteoritic pyroxenes have cell and polyhed

The refinement of the structures of three pyroxenes of composition Di 75 En 10 CaTs 15 , Di 65 En 20 CaTs 15 and Di 70 CaTs 30 synthesized in the range T = 1275-1525°C and P = 14-18 kbar maps out the structural changes occurring in C2/c Di-En-CaTs c

A suite of orthopyroxenes from spinel Iherzolite xenoliths associated with basanites occurring in the Victorian (Australia) post-Pliocene ‘Newer Volcanics’ province was investigated by means of a crystal chemical methodology which provides accura

Equilibrium reversals of Fe 2+ Mg distribution between the M1 and M2 sites of an orthopyroxene from the Johnstown meteorite were achieved at several temperatures between 700 and 1000°C. One single crystal was used for the whole thermal treatment and

The Fe-Mg distribution over the M1 and M2 octahedral sites in five natural orthopyroxenes has been determined by single-crystal X-ray diffraction (XRD) and Mossbauer spectroscopy (MS). The results form the two methods are in good agreement for two Fe
