Fluorcarmoite-(BaNa) was approved in 2015 but to date (June 2022) it has been reported only from the type
At the type locality, Maremola Creek, Isallo, Magliolo, Savona Province, Liguria, Italy, fluorcarmoite-(BaNa) was found in a pebble of the riverbed, associated with quartz and almandine and with microscopic inclusions of fluorapatite and possible graftonite.
