Kaolin is a hydrated aluminum silicate crystalline mineral (kaolinite, Al 2 (Si 2 O 5 ) (OH) 4 ). It was termed 'China clay' from its use in China, formed commonly from weathered granite or hydrothermal activity. It is typical of three main geological environments: (1) weathering profiles; (2) hydrothermal alterations; and (3) sedimentary ...

Kaolinit und eine häufige Übergangsphase, Halloysit, sind typische Produkte der Verwitterung und hydrothermalen Umwandlung. In Sedimenten ist relativ wenig Halloysit aufgrund seiner niedrigen Dehydratationstemperatur und seiner Instabilität bei niedrigem H 2 O-Druck zu finden, während Kaolinit im allgemeinen seit dem Devon überlebt hat.
