The current state of knowledge regarding redox conditions of rocks from asteroidal bodies
(as represented by various classes of meteorites), the Moon and Mars is discussed here. In …

This is a comparative planetary mineralogy study emphasizing the valence-state partitioning
of Cr, Fe, Ti, and V over crystallographic sites in olivine, pyroxene, and spinel from planetary …

The source and nature of carbon on Mars have been a subject of intense speculation. We
report the results of confocal Raman imaging spectroscopy on 11 martian meteorites …

Basalts and basaltic cumulates from Mars (delivered to Earth as meteorites) carry a record of
the history of that planet–from accretion to initial differentiation and subsequent volcanism …

Fe2+–Mg partitioning between olivine and basaltic melt, expressed by the exchange
coefficient, KDol–meltFe–Mg [=(XmeltMg/XolivineMg)/(XmeltFe2+/XolivineFe2+)] is widely …

Twelve samples belonging to the chassignite and nakhlite subgroups of Martian meteorites
were investigated using a variety of micro‐beam analytical techniques to gain insight into …

The primary objectives of this paper are to determine the modal mineralogy of selected low
albedo terrains of different ages ranging from Noachian to Amazonian exposed on the …

The oxygen fugacity of olivine‐phyric martian basalts is estimated using olivine‐pyroxene‐
spinel equilibria, supported by detailed petrography. Results are plotted, along with previous …

We report the concentrations of K, Th, and Fe on the Martian surface, as determined by the
gamma ray spectrometer onboard the 2001 Mars Odyssey spacecraft. K and Th are not …

A group of 32 meteorites, the SNC (Shergotty, Nakhla, Chassigny) group, was derived from
Mars as a product of 4–7 ejection events, probably from Tharsis and Elysium–Amazonis …
