Manandonite
Manandonite is a lithium aluminum silico-borate hydrate member of the Kaolinite-Serpentinite Group. This rare layer silicate occurs as off-white to pale yellow, fan-like lamellar aggregates and globules of platy, orthorhombic (pseudohexagonal) crystals exhibiting a greasy luster. Manandonite was named by A. Lacroix in 1912 for the type locality: Antandrokomby pegmatite, Manandona Valley, Sahatany Pegmatite Field (Mt. Ibity area), Vakinankaratra Region, Antananarivo Province, Madagascar.
