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.

2020年11月28日 · What is Serpentine? Serpentine is a mass of related minerals that commonly consist of chrysotile and antigorite. Serpentine is formed, as a process called serpentinization, where heat and water mixing with low silica igneous rocks such as peridotite and dunite through oxidation and hydrolization…
Serpentinization - Wikipedia
Serpentinization is a hydration and metamorphic transformation of ferromagnesian minerals, such as olivine and pyroxene, in mafic and ultramafic rock to produce serpentinite. [1] Minerals formed by serpentinization include the serpentine group minerals (antigorite, lizardite, chrysotile), brucite, talc, Ni-Fe alloys, and magnetite.
Serpentine subgroup - Wikipedia
Serpentine subgroup is a set of common rock-forming hydrous magnesium iron phyllosilicate ((Mg,Fe) 3 Si 2 O 5 4) minerals, resulting from the metamorphism of the minerals that are contained in mafic to ultramafic rocks. [6] They may contain minor amounts of other elements including chromium, manganese, cobalt or nickel.
