Fluorarrojadite-(BaFe) is a rare phosphate mineral member of the arrojadite group typically found in granitic pegmatites. It is best identified by its green to brownish-green color and its occurrence in phosphate-rich pegmatite nodules, often requiring analytical testing for definitive identification.
