Manandonite - Sold


Manandonite is a chlorite-serpentine type mineral containing lithium and aluminum. Lacroix (1912) named the mineral for the Manandona River, near the original occurrence. For some time, the mineral was believed to be a variety of cookeite (MAC Short Course on Granitic Pegmatites), but later study showed the mineral to have a distinct unit cell and composition (Ranorosa et al. 1989). Zheng and Bailey (1995) solved the crystal structure and established a definite formula for the mineral. Manandonite forms rounded micaceous aggregates to 3 mm across with 2 mm white quartz crystals on this piece.
