Serpentine is a very common mineral, and is found in abundance worldwide. Some famous localities include The Lizard Peninsula, Cornwall, England (the type locality of Lizardite; the Antigorio Valley, Piedmont, Italy (the type locality of Antigorite); and Mount Olympus, Cyprus.

Rock types. Rock type is usually defined as a particular kind of rock having a specific set of characteristics. Rock types are specific assemblages of minerals (most rocks are composed of minerals). Rocks are much more vaguely defined than minerals. Even rocks within one rock type may have a highly variable composition.

- Name describing a small group of green Serpentine minerals rich in nickel. It is also used as definition for a rock containing nickel-rich Serpentine, associated with Talc, Chllorite, and other soft minerals.

Serpentinite is a rock composed of one or more serpentine group minerals. Minerals in this group are formed by serpentinization, a hydration and metamorphic transformation of ultramafic rock from the Earth's mantle. The mineral alteration is particularly important at the sea floor at tectonic plate boundaries.

It all starts with igneous rocks. The Earth is believed to have been entirely molten in its early stages of development. Hence, all other rock types are derivatives of igneous rocks. Some important igneous rocks from left to right: gabbro, andesite, pegmatite, basalt, pumice, porphyry, obsidian, granite, and tuff.

Serpentinization is a geological low-temperature metamorphic process involving heat and water in which low-silica mafic and ultramafic rocks are oxidized (anaerobic oxidation of Fe 2+ by the protons of water leading to the formation of H 2) and hydrolyzed with water into serpentinite.

Serpentinite is formed from olivine via several reactions, some of which are complementary. Olivine is a solid solution between the magnesium-endmember forsterite and the iron-endmember fayalite.

Fibrous Chrysotile, a type of asbestos, should never be brought near the mouth. If its fiber s or particles enter the lungs, they can cause asbestosis. Asbestosis is a lung disease caused by inhalation of asbestos particles, which causes several cancers, particularly lung cancer and mesothelioma.

- Describes a rock composed almost fully of Serpentine minerals, but contains small amounts of pyroxene and amphibole minerals, as well as Olivine, Magnetite, Calcite, and Dolomite. Verde Antique. - Verde Antique is dark green rock composed of Serpentine, and often containing Calcite veins running through it.

The Serpentine group is composed of several related minerals. A generic formula that includes all members is:X2-3Si2O5(OH)4Where X = Mg, Fe2+, Fe3+, Ni, Al, Zn, or Mn.
