Formation of ordinary chondrites

Reviews of Geophysics, 1972
Most of the chemical and mineralogical properties of the ordinary chondrites were established by processes that occurred in the solar nebula during a short time span near the time of formation of the solar system. Four separate and distinct fractionation events appear to have been involved in their formation from more primitive material of mean solar ...

Primordial Rare Gases in Unequilibrated Ordinary Chondrites

Science, 1967
The primordial gases of eight unequilibrated ordinary chondrites are strongly fractionated with respect to "cosmic" proportions. The absolute amounts are roughly proportional to the degree of disequilibration. Apparently, ordinary chondrites originally contained considerably larger amounts of primordial rare gases.

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.

Incompletely compacted equilibrated ordinary chondrites

Meteoritics & Planetary Science, 2009
Abstract— We document the size distributions and locations of voids present within five highly porous equilibrated ordinary chondrites using high‐resolution synchrotron X‐ray microtomography (μCT) and helium pycnometry. We found total porosities ranging from ∼10 to 20% within these chondrites, and with μCT we show that up to 64% of the void space is ...

Trapped xenon in ordinary chondrites

Journal of Geophysical Research: Planets, 1992
A trapped component of heavy noble gases representing a distinct solar system (presumably asteroid belt) reservoir is known to be concentrated in carbonaceous carriers of chondritic meteorites. The isotopic signature of trapped Xe in separates of the H4 chondrite Forest Vale (FV) was determined by combusting its carrier phases at 600°C in oxygen ...

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.
