Dmitryivanovite is a natural mineral composed of calcium, aluminium and oxygen, with the molecular formula CaAl₂O₄. It was reported in 2009^[3] in a calcium-aluminium-rich inclusion in the carbonaceous chondrite meteorite 470 (NWA470) CH3, which landed in North Africa. The mineral name was chosen to ^[4] honor Dmitriy A. Ivanov (1962–1986), a geologist, mineralogist, and petrologist who died on a field expedition.^[3][5][6]
