Pegmatites, greisens, and hydrothermal quartz veins are rocks of late-stage magmatic crystallization. They are the rocks where much of the world's lithium minerals are found. In these rocks, lepidolite occurs as disseminated particles, aggregates of fine grains, “books” of flat sheets, and aggregates of curved sheets.
