Dmitryivanovite is a natural mineral composed of calcium, aluminium and oxygen, with the molecular formula CaAl<sub>2</sub>O<sub>4</sub>. It was reported in 2009 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 honor Dmitriy A. Ivanov (1962âÂÂ1986), a geologist, mineralogist, and petrologist who died on a field expedition.
It is the high-pressure CaAl<sub>2</sub>O<sub>4</sub> dimorph of krotite.
