WebHydrothermal alteration of mafic mantle rock, such as olivine and basalt, creates the metamorphic rock serpentinite, a member of the serpentine subgroup of minerals. This … WebAs this water cools, it interacts with the surrounding rocks, changing both the chemistry of the water and the chemistry of the rocks. This can cause minerals to precipitate from the water. Minerals can also precipitate if the water boils because of a drop in pressure. The precipitated minerals form veins within fractures in the surrounding rock. imaging network of seattleWebMar 15, 2024 · Metamorphism can occur either when a rock moves from one position to another along a single geotherm or when the geotherm itself changes form.
