A rock composed almost entirely of serpentine minerals. Also known as serpentine rock.



(also serpentine rock), a metamorphic rock formed as a result of the serpentinization of ultrabasic rocks and consisting of minerals of the serpentine group. Serpentinite is used as a construction material, in particular, as a facing material; translucent varieties of serpentinite (ophicalcite) are used in industry. Serpentinite occurs in ophiolite zones.
