Mg3Si2O5(OH)4
Monoclinic
Clinochrysotile, a magnesium silicate hydroxide mineral of the serpentine group, was first reported by Aristarain et al. (1974), who found it associated with Franklin roweite and noted that it may occur in parallel growth or in complex intergrowths with roweite; this has not been investigated by the writer. The serpentine reported by Shannon and Larsen (1926) is clinochrysotile, and that described as chrysotile by Foshag (1926) is largely clinochrysotile. It has also been found as pseudo-octahedral inclusions in Sterling Hill franklinite (Francis, 1990).
Clinochrysotile is the dominant serpentine- group mineral at both ore deposits, occurring in late-stage veins and as replacements.
