Krinovite (pronounced kreen'-off-ite) is an emerald-green triclinic meteorite mineral, containing chromium, magnesium, oxygen, silicon, and sodium, of the aenigmatite group. [2] [3] "It has been discovered within graphite nodules in three iron meteorites," specifically the Canyon Diablo, Wichita County, and Youndegin meteorites. [4] It was named in honour of Evgeny Leonidovich Krinov, Russian investigator of meteorites. [5] It is a decaoxotrisilicate in the sorosilicate subclass.
