Serpentine Subgroup

This page is currently not sponsored. Click here to sponsor this page.
D3[Si2O5](OH)4 D= Mg, Fe, Ni, Mn, Al, Zn
Serpentine was named in 1564 by Georgius Agricola (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, usually with divalent cations dominating in octahedrally coordinated sites.
The most common species are all Mg-dominant: lizardite, chrysotile and antigorite.
