Diaspore was transformed from gibbsite. The underlying dolomite is the precursor rock of the Lindai bauxite deposit. The hydrogeological conditions play an important role in bauxite mineralization. Acidic, reducing, and organic materials are essential hydrogeological conditions. The “coal–bauxite–iron” structure greatly promoted the karstic bauxite formation.
