Stable isotope ratios of H, C, and O are powerful indicators of a wide variety of planetary geophysical processes, and for Mars they reveal the record of loss of its atmosphere and subsequent interactions with its surface such as carbonate formation. We report in situ measurements of the isotopic ratios of D/H and (18)O/(16)O in water and (13)C/(12)C,… (More)
We present the first single-shot images of a laser-driven shock wave interacting with micron-scale materials inhomogeneities taken with an X-ray free electron laser. Materials dynamics under high strain-rate loading is important to a range of problems.
Introduction: The nakhlite group of Martian meteorites represent an unusual high Fe, low Al magma composition. However, with seven meteorites now recognized, perhaps from multiple flows , finding a source region becomes more important. Several authors have derived possible parent magma compositions for the nakhlites based on different techniques:… (More)
