Topics discussed include the petrology and geochemistry of the moon, the geology of the moon, lunar regolith processes and resources, the petrology and geochemistry of achondrites, comets and interplanetary dust, shock and terrestrial cratering, the geology of Mars, and the geology of Venus. Papers are presented on silicate liquid immiscibility in isothermal crystallization experiments; highly evolved and ultramafic lithologies from Apollo 14 soils; the relationship between orbital, earth-based, and sample data for lunar landing sites; and the volcanotectonic evolution of Mare Frigoris. Attention is also given to glass variants and multiple HASP trends in Apollo 14 regolith breccias, the characterization of lunar ilmenite resources, the U-Th-Pb systematics of the Estherville mesosiderite, and the extraterrestrial halogen and sulfur contents of the stratosphere. Other papers are on argon-40/argon-39 dating of impact craters; the outliers of dust along the southern margin of the Tharsis region, Mars; and the geology of southern Guinevere Planitia, Venus, based on analyses of Goldstone radar data.
