a rock in which the mineral serpentine has replaced other minerals as an alteration product, usually do to hydrothermal actions in the late stages of the rocks formation.
A rock consisting almost wholly of serpentine group minerals (such as antigorite and chrysotile) that are derived from the alteration of ferromagnesian silicate minerals such as olivine and pyroxene. Serpentinites are often derived from the alteration of peridotites.
A green metamorphic rock composed of hydrated magnesium silicates formed by the alteration of olivines and pyroxenes usually in a submarine environment.
A rock consisting primarily of serpentine.
Igneous or metamorphic rock chiefly composed of serpentine minerals such as chrysotile or lizardite. Chrysotile, when found, can occur in localities with serpentinite rock.
altered rock formed by low temperature and water interaction and consisting mainly of hydroxyl-bearing magnesium silicates formed from olivine and pyroxenes
(150) - Green to greenish-yellow rock composed chiefly of the mineral serpentine, derived from metamorphism of iron-magnesium-rich igneous rocks.
Subject: rock Green, black or reddish rock composed predominantly of serpentine minerals. Formed by hydration of of igneous or metamorphic peridotites.[ Pics List
Serpentinite is a rock comprised of one or more serpentine minerals. Minerals in this group are formed by serpentinization, a hydration and metamorphic transformation of ultramafic rock from the Earth's mantle. The alteration is particularly important at the sea floor at tectonic plate boundaries.
