Meteorites

Davisite is likely a product of condensation/evaporation within the solar nebula (Mindat).

Localities

At the type locality, the Allende meteorite, Pueblito de Allende, Chihuahua, Mexico, davisite occurs as a fine-grained aggregate with rare-earth-element-rich perovskite; it is the main phase in ultra-refractory domains within olivine. Associated Minerals include spinel and perovskite (Mindat).
