- (The process of mineral alteration to kaolin.)
Advanced Usage
"Complete kaolinization": refers to the thorough conversion of all susceptible minerals in a rock mass into kaolin.
- In tropical regions, complete kaolinization of feldspar-rich rocks is common. (Total transformation of feldspar into kaolin.)
"Hydrothermal kaolinization": kaolinization caused by hot, circulating groundwater.
- Hydrothermal kaolinization often creates large, economically valuable clay deposits. (Kaolin formation from hot water activity.)
