Planetary materials science and astrobiology... This work therefore represents, in a broad sense, an exploration of the astrobiological implications of planetary materials including likely precursors to terrestrial planets (enstatite chondrites); and important possible planetary habitats including post-impact hydrothermal mineral deposits and their associated weathering assemblages; and the fossilization of records of an ecosystem based on the microbial leaching of seafloor basaltic glass
