Abstract
Existing wet chemical analyses and structural studies of the serpentine minerals, chrysotile, lizardite, and antigorite suggest that these minerals have different chemical compositions and could be identified by composition alone. Triangular composition diagrams, a statistical treatment of the oxide components, MgO, FeO, Fe2O3, A12O3, and H2O, and calculated mineral formulae from chemical analyses all suggest that chrysotile, lizardite, and antigorite are not polymorphs. Antigorite is distinguished by its comparatively low H2O and high SiO2 contents. Chrysotile is characterized by a relatively high H2O and MgO content and by a small ratio of Fe2O3 to FeO; while lizardite has high SiO2 and low FeO contents.
