The name traditionally applied to three hydrated magnesium silicate minerals, antigorite, chrysotile and lizardite. All have similar chemical compositions [ideally Mg3Si2O5(OH)4] but with three different but closely related layered crystal structures. Serpentine also has been used as a group name for minerals with the same layered structures but with a variety of compositions. The general formula is M3T2O5(OH)4, where M may be magnesium (Mg), ferrous iron (Fe2+), ferric iron (Fe3+), aluminum (Al), nickel (Ni), manganese (Mn), cobalt (Co), chromium (Cr), zinc (Zn), or lithium (Li); and T may be silicon (Si), Al, Fe3+, or boron (B).
