Kingsmountite is a secondary mineral formed by the oxidation of
primary phosphates by descending oxidising ground water in complex
At Vasin-Myl'k Mt, Voron'i Tundry, Murmansk Oblast, Russia, kingsmountite is associated with eosphorite, laueite, lun'okite, fairfieldite and mitridatite (HOM).
At the type locality, the Foote Lithium Company Mine, Kings Mountain Mining District, Cleveland county, North Carolina, USA, kingsmountite occurs in phosphate mineralised fractures in granite pegmatite, associated with mitridatite, mangangordonite, birnessite and albite (Mindat, Dana, HOM).
At the Tip Top mine, South Dakota, USA, kingsmountite is associated with whitlockite and cyrilovite (HOM).
