WebSerpentinite 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. Serpentinite reactions 1a and 1b, below, exchange silica between forsterite and fayalite to form serpentine-group minerals and magnetite. WebThe primary mineral in serpentinite is serpentine, a mineral rich in magnesium and iron. Serpentinite is a metamorphic rock that formed when the minerals in a preexisting rock, like dunite, are altered when exposed to water beneath Earth’s surface.
