The Yichun Ta-Nb-Li mine is situated within a small, sheetlike body of topaz-lepidolite granite which is the most fractionated phase of the Yashan batholith. Volumetrically, the most important phase in the batholith is a coarse-grained, protolithionite-muscovite granite which has a finer grained, muscovite granite margin.
