Compositional analyses of meteorites: using the facilities of the plasma mass spectrometry laboratory a student would analyze meteoritic samples for their chemical and or isotopic compositions. Bulk solution analyses, in-situ, spatially resolved analyses, or both can be carried out; the choice will be dictated by the hypothesis to be tested. A number of specific experiments are on offer, including but not limited to (1) element partitioning between phases in meteorites, (2) element fractionation in the early cosmos, and (3) Li isotopic composition of phases in a meteorite. Students are encouraged to contact Bill McDonough for further info.
