Localities
At the type locality, Alluaiv Mountain, Lovozersky District, Murmansk Oblast, Russia, natroxalate occurs as
granular nodules up to 2 cm across, as veinlet-like segregations, as columnar crystals 3 to 5 mm long and up to 1 mm
thick, and as radiating aggregates of the crystals. The natroxalate occurs as a hydrothermal phase in ultra
agpaitic
pegmatites. Associated minerals are
albite, aegirine,
elpidite, nenadkevichite,
tainiolite, natron,
pyrite, sphalerite and
galena
(AM 82.430-433).
