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, 1980The 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, 1984The 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, 1982Olivine 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.

Olivine nodules in olivine nephelinite from Tokatoka, Northland
New Zealand Journal of Geology and Geophysics, 1965Abstract Petrographic descriptions and a chemical analysis are presented of an olivine nephelinite occurring as a dike in argillaceous limestones and in regional association with a Miocene basalt‐andesite‐dacite igneous suite. The mineralogy and possible origin of olivine nodules carried by the nephelinite are discussed.

Formation conditions of pyroxene-olivine and magnesian olivine chondrules
Geochimica et Cosmochimica Acta, 1990Dynamic crystallization experiments performed on a Type I and an intermediate Type II/III composition demonstrate chondrule texture is controlled by the abundance of heterogeneous nuclei. This factor is controlled by the maximum initial temperature relative to the olivine disappearance temperature for the given heating time.

Welding of olivine was demonstrated by grinding it in a ball mill in an atmosphere of about 2 × 10 -7 torr. Most of the sample adhered strongly to the container and grinding balls although adhesion in air is only slight.

The greenhouse effect, thanks mainly to the water vapor in our atmosphere, has created a livable climate on Earth. Climate change, however, may potentially have dire consequences. It is generally assumed that the rise in CO2 levels in the atmosphere is the main culprit, although several other greenhouse gases (GHG) also play a role.
