Nickel–manganese variability in olivine and Al‐in‐olivine thermometry for olivine‐phyric shergottites

Meteoritics & Planetary Science, 2021
AbstractOlivine‐phyric shergottites represent primitive Martian magmas, but they commonly contain excess olivine and rarely represent primary mantle melts. Olivine chemistry, however, tracks magma evolution and preserves information on the original parent magma composition.

Olivines and olivine coronas in mesosiderites

Geochimica et Cosmochimica Acta, 1980
The paper presents a study of olivines and their surrounding coronas in mesosiderites texturally and compositionally using optical and microprobe methods. Olivine composition ranges from Fo(58-92) and shows no consistent pattern of distribution within and between mesosiderites; olivine occurs as large single crystals or as partially recrystallized ...

Sintering of olivine and olivine-basalt aggregates

Physics and Chemistry of Minerals, 1984
The sintering behavior of olivine and olivine-basalt aggregates has been examined at temperatures near 1,300° C. Experimental factors contributing to rapid sintering kinetics and high-density, fine-grained specimens include: (i) the uniform dispersion of basalt throughout the specimen, (ii) a very fine, uniform particle size for the olivine powder ...

Olivine phenocrysts of Hawaiian olivine tholeiite and oceanite

Contributions to Mineralogy and Petrology, 1982
Olivine phenocrysts of Hawaiian tholeiites display a variety of textures and a variation in composition which is due to supercooled crystallization. The highest forsterite content measured is 91%, and the highest magnesia content estimated for a tholeiitic liquid is 17%, using the olivine geothermometer.
