Kaolinite is a clay mineral, part of the group of industrial minerals, with the chemical composition Al 2 Si 2 O 5 (OH) 4.It is a layered silicate clay mineral which forms from the chemical weathering of feldspar or other aluminum silicate minerals. It is a layered silicate mineral, with one tetrahedral sheet of silica (SiO 4) linked through oxygen atoms to one octahedral sheet of alumina (AlO

Kaolinite: The clay mineral kaolinite information and pictures

Kaolinite is a clay mineral, with a soft consistency and earthy texture. It is easily broken and can be molded or shaped, especially when wet. Kaolinite is a lackluster and uninteresting mineral on its own, but it occasionally forms interesting pseudomorphs, especially after feldspars. It is also a common accessory to other minerals, including gem crystals in decomposing feldspar pegmatites.
