Colquiriite is a rare lithium-bearing mineral in hydrothermal tin-bearing veins (Webmin, HOM). Associated minerals include
sphalerite, madocite and
At the type locality, the Colquiri mine, Inquisivi Province, La Paz, Bolivia, colquiriite has been found in a tin mine associated with sphalerite, pyrite, madocite, hydrokenoralstonite and gearksutite (Mindat, AM 66.879). In a single specimen examined hydrokenoralstonite appears to replace colquiriite and gearksutite is present as veinlets, so that colquiriite appears to be the oldest of the fluorides (AM 66.1099).
