Lithium isotope constraints on crust?mantle interactions and surface processes on Mars
Original language description
Li abundances and isotope compositions are reported for a suite of martian meteorites that span the range of petrological and geochemical types recognized to date for Mars. Samples include 21 bulk-rock enriched, intermediate and depleted shergottites, 6nakhlites, 2 chassignites, the orthopyroxenite ALH 84001 and the polymict breccia NWA 7034. Shergottites unaffected by terrestrial weathering exhibit a range in d7Li from 2.1 to 6.2?, similar to that reported for pristine terrestrial peridotites and unaltered MOR and OI basalts. Two chassignites have d7Li values (4.0?) intermediate to the shergottite range, and combined, these meteorites provide the most robust current constraints on d7Li of the martian mantle. The polymict breccia NWA 7034 has the lowest d7Li (?0.2?) of all terrestrially unaltered martian meteorites and may represent an isotopically light surface end-member. The new data for NWA 7034 imply that martian crustal surface materials had both a lighter Li isotope composition
