  • Bauxite ore Britannica

    Bauxites vary physically according to the origin and geologic history of their deposits: some deposits are soft, easily crushed, and structureless some are hard, dense, and pisolitic, or pealike still others are porous but strong or are stratified or largely pseudomorphic after their parent rock. The laterite type is commonly

    The other type is associated with limestones. This type of bauxite is known as karst bauxite because it accumulates in karst solution depressions within limestone plateaux. These depressions act as sediment traps where either eolian or fluvial aluminumbearing sediments can accumulate to be later altered to bauxite.
