|Name:||Serpentine was named in 1564 by Georgius Agrigola (Georg Bauer) from the Latin "serpens" = snake in allusion to the mottled green appearance of the mineral suggesting the resemblance to some snakes.|
Serpentine is a subgroup 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.
