By long time physical and chemical process, the carbonate rock after Central Guizhou uplift, becomes red clay, after further weathering, the red clay decomposed into the oxide, hydroxide of Al and Fe, in the dissolution hole and depression, it concentrates primary fragmentary tight and earthy karst bauxite ore. Because the variation of landform, it decomposes and cracks again, affords the material source: bauxite fragment for the formation of Maochang bauxite deposit. These bauxite fragment and oxide of Al, Fe are transported into the Maochang dissolution lakes by underground and surface water in different forms, forms Maochang ancient dissolution sedimentary bauxite deposit as the sedimentary regulation of fragment, chemistry and biology.
