When considering the rheology of a suspension the fundamental physical aspect to be
quantified is the redistribution of strain between the deformable matrix fraction of the …

Olivine, pyroxene and garnet are nominally anhydrous but can accommodate tens to
hundreds of parts per million (ppm) H2O or “water” in the form of protons incorporated in …

Reconciling the geology of Mars with models of atmospheric evolution remains a major
challenge. Martian geology is characterized by past evidence for episodic surface liquid …

Martian meteorites are the only direct samples from Mars, thus far. Currently, there are a total
of 262 individual samples originating from at least 11 ejection events. Geochemical …

We report data on the martian meteorite Northwest Africa (NWA) 7034, which shares some
petrologic and geochemical characteristics with known martian meteorites of the SNC (ie …

Chemical disequilibrium in planetary atmospheres has been proposed as a generalized
method for detecting life on exoplanets through remote spectroscopy. Among solar system …

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 …

Return of samples from the surface of Mars has been a goal of the international Mars
science community for many years. Affirmation by NASA and ESA of the importance of Mars …

The search for water in our solar system is one of the primary driving forces for planetary
science and exploration because water plays an important role in many geologic processes …

We conducted a petrologic study of apatite within 12 Martian meteorites, including 11
shergottites and one basaltic regolith breccia. These data were combined with previously …
