Pegmatites

Touretite was approved in 2024 and is pending publication. To date (December 2024) it has been reported only from the type locality.

Localities

At the type locality, the Ambalabe pegmatite, Manapa pegmatite Field, Anosiarivo Manapa, Betafo District, Vakinankaratra, Madagascar, touretite is the first mineral with essential Li, Be, and B, and is a member of the londonite-rhodizite series. Madagascar so far hosts the only known localities that produced large gem-quality crystals of londonite-rhodizite, all specimens having been recovered from a shallow and narrow but long pegmatite dike (AM 109.12.2173).
