| Abstract: | Lateritic crust of basalts is of zonal texture.This paper describes the cha-racteristics of minerals and rocks in each zone of lateritic crust,and indicates that the separation of Al from Si and Fe from Al as well as migration,concen-tration and dispersion of elements during weathering play important roles in the formation of bauxite.Samples from each zone are systematically observed with scanning electron microscope and energy dispersion pectrum.Weathering and evolution of elements are also discussed in this paper.Author considers that gibbsite can be formed through many ways during different stages of weathering. |
