Physical properties
Hardness of 2.5-4 on Mohs scale, pink to purple color, pearly luster, and perfect basal cleavage. It forms in monoclinic crystal systems.
Formation & geological history
Formed in lithium-rich granitic pegmatites and high-temperature hydrothermal veins.
Uses & applications
Primary ore of lithium, used in glass manufacturing, and collected as mineral specimens.
Geological facts
Lepidolite is often associated with other lithium-bearing minerals like tourmaline and spodumene. Its distinct lilac color comes from trace amounts of manganese.
Field identification & locations
Identified by its characteristic purple-pink color and micaceous flaky cleavage. Commonly found in Madagascar, Brazil, and the USA.
