Bikitaite is one of very few very few lithium-bearing zeolites.
It occurs as a late-formed mineral in fractures in lithium-rich
pegmatites (Webmin, Mindat, HOM) and forms prior to stilbite
(Dana). Common associates include albite,
bavenite and quartz
At King's mountain, North Carolina, USA, bikitaite is found in lithium-rich pegmatites occurring sparingly as single crystals in seams. The pegmatites are mined for spodumene. They are intruded into thin-layered amphibolite and fine-grained mica schist, and are mainly composed of microcline, albite, quartz, spodumene and muscovite. Minor fractures contain quartz, albite, rhodochrosite and a number of phosphates, including apatite, vivianite and fairfieldite. In several of these fractures bikitaite has been found in small amounts, associated with albite, quartz, apatite and fairfieldite (AM 53.1202).
At the type locality, the Nolan property, Bikita Area, Masvingo, Zimbabwe, bikitaite occurs in a granite pegmatite associated with eucryptite, quartz, petalite, feldspar, calcite, stilbite and allophane (HOM).
The assemblages of minerals in the pegmatite were deposited in succession from petalite + quartz to spodumene + quartz to eucryptite + quartz (R&M 92.2.153).
