Abstract

The mineralogy and geochemistry have been studied in three representative lateritic weathering covers close to the Tropic of Cancer (Guangxi, South China) with the purpose of studying formation and evolution processes of lateritic covers in this region. The X-ray diffraction and scanning electron microscope analysis results indicate that the contents, particle sizes, shapes and structures of secondary minerals, such as iron and clay minerals, are distinctly different in ferruginous nodular horizon and mottled clay layer of lateritic profiles. Finally, a model for the formation and evolution of typical lateritic weathering covers in south-central Guangxi, supported by all the data, was proposed
