Genetic classification of kaolin
Based on the formation of kaolin deposits, according to the differences in metallogenic geology, geographical conditions, deposit scale, ore body morphology and occurrence characteristics, and ore material composition, the kaolin ore geological exploration standard has divided China kaolin deposits into three types and six subtypes according to the different mineralization.
◆ Weathering type: weathering residual subtype and weathering subtype.
◆ Hydrothermal alteration is divided into hydrothermal alteration subtypes and modern hot spring alteration subtypes.
◆ Sedimentary types: sedimentary and sedimentary weathering subtypes and kaolinite subtypes in coal bearing strata.
