The successive decrease of smectite expandability is a reliable marker of depth effect (Chamley, 1997). The zone where smectite swelling layers in illite/smectite particles are modified into illite layers is often described as the zone of thermal illitization of smectite, or smectite disappearance zone (Kubler, 1997).
