Serpentinite - Wikipedia
Serpentinite is a metamorphic rock composed predominantly of serpentine group minerals formed by serpentinization of mafic or ultramafic rocks. The ancient origin of the name is uncertain, it may be from the similarity of its texture or color to snake skin. [ 1 ]
Serpentine: mineral, gem, ornamental stone, asbestos source
Serpentine is a group of minerals that are usually green in color. It is used as gemstone, architectural stone, carving material and source of asbestos. Serpentinite is a rock composed mainly of serpentine minerals.
Serpentinite - Metamorphic Rocks - Sandatlas
Serpentinite is a metamorphic rock that is mostly composed of serpentine group minerals. Serpentine group minerals antigorite, lizardite, and chrysotile are produced by the hydrous alteration of ultramafic rocks.
Serpentinite FAQ - Golden Gate National Recreation Area (U.S.
2015年2月28日 · Serpentinite is a metamorphic rock that forms at tectonic plate boundaries deep within the Earth. In the Franciscan Complex, it formed when ocean water carried down with subducting ocean crust was heated and moved through upper mantle and basal ocean crust rocks, hydrating their magnesium- and iron-rich minerals, like olive and pyroxene, to ...

Serpentinization - Wikipedia
Serpentinization is a form of low-temperature (0 to ~600 °C) [5] metamorphism of ferromagnesian minerals in mafic and ultramafic rocks, such as dunite, harzburgite, or lherzolite. These are rocks low in silica and composed mostly of olivine ((Mg2+, Fe2+)2SiO4), pyroxene (XY (Si,Al)2O6), and chromite (approximately FeCr2O4).
Serpentine subgroup - Wikipedia
Serpentine subgroup (part of the kaolinite-serpentine group in the category of phyllosilicates) [1] are greenish, brownish, or spotted minerals commonly found in serpentinite. They are used as a source of magnesium and asbestos, and as decorative stone. [5]
Serpentinite - an overview | ScienceDirect Topics
Serpentinite (Fig. 7.12) is a metamorphic rock mostly composed of one or more of the serpentine group minerals that include antigorite, lizardite, and chrysotile. The serpentinite depicts fascinating shades of green color and usually layered and banded.
Serpentinite - ALEX STREKEISEN
serpentinization (is a geological low-temperature metamorphic process ) involves chemical reactions which convert unhydrous ferromagnesian silicate minerals (pyroxene, olivine) into hydrous silicate minerals (serpentine) plus some other possibilities like brucite and magnetite.
Serpentine |Physical-Optical Properties, Occurrence, …
2023年8月24日 · Serpentine is the common name of a group of minerals. Apart from the main members of Antigorite and Chrysotile, there is usually no distinction between individual members except for scientific study and classification. Antigorite generally represents more solid forms, and Chrysotile often represents fibrous forms, especially asbestos.
