A group of minerals, hydrous magnesium
silicate, Mg3Si2O5(OH)4, occurring in soft
metamorphic rocks and usually dark green. The
fibrous form chrysotile is a source of
asbestos; other forms are antigorite, talc,
and meerschaum. Serpentine minerals are
formed by hydration of ultrabasic rocks
during metamorphism. Rare snake-patterned
forms are used in ornamental carving.
