The Kenna ureilite - An ultramafic rock with evidence for igneous, metamorphic, and shock origin
TLDR
Kenna ureilite as discussed by the authors is a typical UREILite with the requisite mineralogical and chemical properties of the group, including a greater density, the occurrence of exceedingly minute quantities of feldspar, and a very strong elongation lineation of the silicate minerals.About:

Mineralogy of meteorite groups
TL;DR: For example, the authors identified 275 mineral species have been identified in meteorites, reflecting diverse redox environments, and, in some cases, unusual nebular formation conditions, including the presence of complex organic compounds, magnetite, and carbonates.

Ureilites - A critical review
TL;DR: In this paper, the authors discuss the current state of understanding of the petrogenesis of ureilites (which are ultramafic rocks considered to be products of a common planetary differentiation process), identify areas in which basic knowledge is lacking and suggest directions for future work on these rocks.

The Chassigny meteorite: a cumulate dunite with hydrous amphibole-bearing melt inclusions
TL;DR: The Chassigny meteorite as discussed by the authors is a moderately shocked olivine achondrite or chassignite with features indicative of a cumulate origin with some subsolidus annealing.
Journal ArticleDOI
Formation of ureilites by nebular processes
TL;DR: Oxygen isotopic data for 23 ureilites, including 14 Antarctic meteorites, were presented in this paper, showing that the isotopic and chemical variations are due primarily to processes in the solar nebula and not to igneous processes within a parent body.

Empirical Correction Factors for the Electron Microanalysis of Silicates and Oxides
A. E. Bence,Arden L. Albee +1 more
TL;DR: In this paper, the calibration curve in a binary metal alloy system can, within the variance of data points, be described by the linear expression $$C_{A}/K{A} = \alpha_{AB} + (1 - α_{AB})C{A]$$, where C is the concentration of element A in alloy  relative to pure A, and K is the background-corrected intensity of a characteristic radiation line of A in the alloy relative to that of pure A. This linear variation of the correction factor with composition can be extended to multicomp

TL;DR: Signer and Suess as discussed by the authors brought together and evaluated all significant evidence on the origin of meteorites, and showed that the absence of a Widmanstatten pattern in meteorites with > 16% Ni cannot be attributed to high pressures, but to supercooling or an unusually fast cooling rate for these meteorites.

High Temperature Flow of Dunite and Peridotite
TL;DR: In this article, the steady state deformation of dunite and peridotite was investigated in solid pressure media in the presence and absence of externally released H 2 O. The steady state data were best fit by a power creep equation with the stress exponent, n ≃ 2.4 and 4.8 and the creep activation energy, Q ≃ 80 and 120 Kcal/mole, respectively.
