Pegmatites

Darapiosite was first published in 1975, but to date (May 2025) it has been reported only from the type locality.

Localities

At the type locality, the Dara-i-Pioz Massif, Districts of Republican Subordination, Tajikistan, darapiosite occurs in masses up to 0.5 cm across in glacial moraine derived from the alkalic massif. Associated minerals include aegirine and quartz, as well as sogdianite, eudialyte, schizolite and polylithionite (AM 61.1053-1054, HOM).
