Rock formed by hydration and metamorphic transformation of olivine / From Wikipedia, the free encyclopedia
Serpentinization is a hydration and metamorphic transformation of ferromagnesian minerals, such as olivine and pyroxene, in mafic and ultramafic rock[1]. Minerals formed by serpentinization include the serpentine group minerals (antigorite, lizardite, chrysotile), brucite, talc, Ni-Fe alloys, and magnetite[1][2]. The mineral alteration is particularly important at the sea floor at tectonic plate boundaries.[3][4]
