At the type locality, Selsurt Mountain, Lovozersky District, Murmansk Oblast, Russia, kuzmenkoite-Mn occurs in minute cavities in albitised murmanite-bearing lujavrites. It is a late hydrothermal phase associated with natrolite, labuntsovite, calciohilairite, vinogradovite and carbonate-rich fluorapatite. Minerals formed earlier include aegirine, albite, eudialyte, lorenzenite, murmanite, magnesio-arfvedsonite, microcline and nepheline. Kuzmenkoite-Mn also occurs as pseudomorphs of murmanite. (AM 85.1562).
