摘要

In this paper, the authors reviewed research of bauxite geology from the aspects of deposit classification, orebody morphology and structures, mineral composition, source rocks, ore-forming environ- ments and mechanisms. Some features of the bauxite deposits in China are also illustrated, and new research methods and opinions obtained in recent years are further presented. The source rocks of kasrtic bauxite areas can be distinguished by utilizing the U-Pb and Lu-Hf isotopes of the detrital zircons in the bauxite ores. The transportation mechanism of the karstic bauxites in China is regionally varied. In the North China Block, the Carboniferous ores were formed via both ion crystallization and clastic deposition, while the Permian karstic bauxite in the South China Block was dominated by ion crystallization in generation.
