Tungsten in ordinary chondrites

Earth and Planetary Science Letters, 1977
Abstract In ordinary chondrites tungsten displays both lithophile and siderophile characteristics. Its concentration in the metal phase is positively correlated with petrologic type, and with the distribution coefficientKD =W in metal/W in silicates plus troilite.

Chainpur-like Chondrites: Primitive Precursors of Ordinary Chondrites?

Science, 1966
Chainpur and similar, apparently primitive, chondritic meteorites may be precursors of ordinary chondrites; a variety of evidence supports this working hypothesis. In general, carbonaceous chondrites seem to be related collaterally to this genetic sequence rather than being direct ancestors of ordinary chondrites.

Al-rich objects in ordinary chondrites: Related origin of carbonaceous and ordinary chondrites and their constituents

Geochimica et Cosmochimica Acta, 1984
A description is given of 169 Al-rich objects (arbitrarily defined as having 10 wt pct or more of Al2O3) from 24 ordinary chondrites of types 3 and 4, five regolith breccias containing unequilibrated material, the unique meteorite Kakangari, and a few ordinary chondrites of types 5 and 6.

Crystallization of chondrules in ordinary chondrites

Geochimica et Cosmochimica Acta, 1980
Abstract The process of crystallization and the origin of chondrules are discussed, in terms of the phase relations of the minerals in chondrules in six ordinary chondrites of the Yamato-74 meteorites, especially the Yamato-74191 (L3). Chondrules are classified into six types.
