Localities

At the Karnasurt Mountain, Lovozersky District, Murmansk Oblast, Russia, kuzmenkoite-(Zn) occurs as a hydrothermal product in a pegmatite as rough crystals up to 3 × 0.5 × 0.3 mm in size. Associated minerals include natrolite, microcline, albite, aegirine, nepheline, arfvedsonite, sodalite, eudialyte, beryllite and elpidite (AM.88.932).

At the Kedykverpakhk Mountain, Lovozersky District, Murmansk Oblast, Russia, kuzmenkoite-(Zn) occurs as a hydrothermal product in a pegmatite and forms pseudomorphs after murmanite. Associated minerals include natrolite, microcline, albite, aegirine, nepheline, arfvedsonite, sodalite, eudialyte and lorenzenite (AM.88.932).

At the type locality, the Lepkhe-Nel'm Mt, Seidozero Lake, Lovozersky District, Murmansk Oblast, Russia, kuzmenkoite-(Zn) occurs as a hydrothermal product in a pegmatite as coarse prismatic crystals up to 0.5× 7 mm. Associated minerals include microcline, aegirine, nepheline, magnesio-arfvedsonite, eudialyte, lorenzenite, lamprophyllite and catapleiite (AM.88.932).
