About Kaolinite SubgroupHide

Formula:
Al2Si2O5(OH)4
Dioctahedral, Al-rich members of the Kaolinite-Serpentine Group.

Within this group kaolinite, dickite and nacrite are actually polytypes of a single species, but the names have been "grandfathered" by the IMA. The species should probably be kaolinite, with -1A (kaolinite), -1M (nacrite), and -2M (dickite) polytypes. Most of the species in this group have multiple polytypes due to stacking sequence variations.
