The genetic type classification of the bauxite deposits in China was oversimplified in the past and the author tries to make a relatively detailed division based on their practical conditions. First, the occurrences of bauxite deposits are divided into platform and geosyncline terrains according to their geotectonic setting. Then, the lateritic, accumulated, sedimentary, solution precipitated diagenetitc-epigenetic, regional metamorphic categories and two metacategories are established based on their main metallogenetic processes. Finally 21 types and 9 metatypes are set up according to their formation features (including genesis, sedimentary environment or major mineral features), of which several types are newly established. The classification is quite different from that of the world’s bauxite deposits, the metacategories and metarypes refer to the deposits o only scientific significance at present.
