Bauxite is a sedimentary rock. A sedimentary rock is a rock that is made up of compacted and compressed sediment (dirt, sand, rocks, fossil, debris). After rocks, sand, dirt and other sediment is eroded and weathered through air, wind or waterways, all this sediment begins to pile up layer after layer.
Bauxite is a weathering product of aluminum-bearing rocks (usually igneous rocks ). Bauxite is either pale pink, orange, or reddish rock, which often contains rounded concretionary masses of aluminum hydroxides and iron (hydr)oxides. These are known as pisoliths.
