... crystal structures observed using in situ micro X-ray diffraction quantifies the shock deformation as a full width half maximum (FWHMχ) of 3.38° ± 1.13° (16 reflections from seven olivine grains), consistent with shock stage S3 ordinary chondrites. Wood Lake is confirmed as a new Canadian meteorite find...

... in light of these findings. In the present study, we set out to find coexisting igneous apatite and merrillite in a martian meteorite to compare their volatile abundances and determine if a whitlockite component exists in martian merrillite. It has been postulated that whitlockite and whitlockite...

Excluding Earth, Mars is the most promising destination in the inner solar system to find water, as it is undoubtedly responsible for shaping many geomorphologic features observed on the present-day martian surface; however...

.... The major elements, REE, Sr, and Eu 3+ /Eu 2+ were determined for merrillite and whitlockite from planetary mineral assemblages that exhibit strikingly different oxygen fugacities (IW-1 to approximately FMQ+1). These samples included a mare basalt (15058), KREEP basalt (15386), martian basalts (meteorites...

... requires that the spinel-olivine pairs were in equilibrium when the partitioning of V occurred. We have applied the V spinel-olivine oxybarometer to the Y98 meteorite as a test of the method. We calibrated four oxybarometers based on the multivalent behavior of V for a Y98 proxy composition. We...

The most important results from analysis of pyroxene in martian meteorites (e.g., QUE 94201) are the oxygen fugacity estimates of IW+0.2 and IW+0.9 derived from partitioning and valence data for Cr and V, respectively, obtained from experiments using appropriate...

.... These experiments are specifically targeted for an olivine-rich martian basalt composition that was modeled after the bulk chemistry of the meteorite Yamato 980459 (i.e., Y-98). The chromium valence ratio in the olivine crystals was measured with X-ray absorption near edge spectroscopy (XANES) at the Advanced...

This carbon has been shown to form inorganic compounds under reducing conditions at elevated hydrogen fugacity ( Eck et al. 1966 ), and these conditions would be consistent with those of the vapor plume surrounding a lunar pyroclastic fire-fountain eruption...

.... Xirouchakis et al. (2001) examined symplectites in the Los Angeles meteorite. However, the symplectites they examined were composed of olivine + augite, and they did not find any SiO 2 phase present. They use the lack of an SiO 2 phase to argue against pyroxferroite as a precursor to the symplectites...
