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

Sediments and sedimentary processes on the Moon and Earth are very different. In the absence of water, an atmosphere, the magnetosphere, and much less oxygen in its rocks, the Moon has neither clay minerals nor carbonates, and no Fe3+. Mechanical wea
