Nice explanation, thanks @Shahin VX.

Kaolin is chemically classified as an argillaceous rock. This classification is based on its primary composition of kaolinite, a clay mineral. Argillaceous rocks are rich in clay minerals, which are formed from the weathering of silicate minerals and are characterized by their fine-grained texture.

Kaolin, also known as china clay, forms from the chemical weathering of feldspar-rich rocks and is commonly used in ceramics and as a filler in various products.
