Dust from collisions: mid-infrared absorbance spectroscopy of Martian meteorites

Mid-infrared transmission/absorbance spectra of a representative range of martian meteorites are presented. The data is used for mineralogical bulk studies, but also for the comparison with astronomical dust spectra

Petrography and bulk composition of Miller Range 05035: a new lunar VLT gabbro

Miller Range (MIL) 05035 is a crystalline lunar mare gabbroic meteorite collected in Antarctica in 2005 [1]. It is an important new sample in the lunar meteorite (LM) collection as it is only one of ~8 to be classified as basaltic in nature. MIL 05035 is coarsely grained with large pyroxene grains ( 8mm) subophitically enclosing plagioclase grains ( 6mm), and accessory ilmenite, spinel, silica and sulphide phases

Alteration of the Nakhlite Lava Pile: was water on the surface, seeping down, or at depth, percolating up? Evidence (such as it is) from carbonates

We present carbon and oxygen isotope data on carbonates in five nakhlites and use the results to interpret the martian weathering processes

Mineralogy and Geochemistry of Shergottite RBT 04262

This abstract presents mineralogical and geochemical data on newly discovered shergottite RBT 04262 and compares it with other known shergottites
