As an example of how strange these Lovozero "pegmatites" can be, one of them, which Pekov calls "the narsarsukite occurrence," has a groundmass composed of albite, aegirine, lorenzenite, eudialyte and neptunite, with veins of massive narsarsukite up to 2 meters thick.
Associated minerals are: aegirine, albite, analcime, ancylite-(Ce), calcite, catapleiite, dawsonite, donnayite-(Y), elpidite, epididymite, eudialyte, eudidymite, fluorite, franconite, gaidonnayite, galena, genthelvite, gmelinite, gonnardite, horvathie-(Y), kupletskite, leifite, microcline, molybdenite, narsarsukite, natrolite, nenadkevichite, petersenite-(Ce), polylithionite, pyrochlore, quartz, rhodochrosite, rutile, sabinaite, serandite, siderite, sphalerite, thomasclarkite-(Y), zircon and an unidentified Na-REE-carbonate (UK91).
beige, gray, and occasional pink: closer inspection revealed some excellent small-thumbnail catapleiite, narsarsukite, donnayite, nepheline, serandite, genthelvite, rhodochrosite, etc., etc.
