Diapirism and the origin of high TiO2 mare glassesHigh TiO2 mare picritic glasses are derived from cumulate source regions that are only modestly endowed with ilmenite-enriched crystallization products. These sources are mobilized by the heat derived from the primitive interior and evolve into diapirs which rise adiabatically from depths in excess of 700 km. As these diapirs undergo pressure-release melting, they also stir in significant portions of the surrounding mantle.
