| Abstract: | In this study the author has discovered the complexity of composition in bauxite.The Al2O3 content is not very high, but widely changes.Fe2O3 is high and greatly varies.The bauxite is mainly derived from weathered residuum of basal clay sandstone, deposited in lagoon envirnment.The fabric of bauxite ore is also very special.Fragments are of ten angular with plastic deformation.There are sev-eral kinds of pisolite and oolite in bauxite.Some of them are larger with many contraction fissures, si-miliar to those in Australia lateritic bauxite.Some are in medium size with many layers.Others are small, rich in Fe2O3.there is an irregular erosional surface between clastic and massive bauxites.The thickness of clastic bauxite is very changeable.Furthermore, graded structure is found in clastic bauxite.It is suggested that the bauxite is typical sediment of storm. |
