How does hydrothermal metamorphism occur
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. WebHydrothermal metamorphism can also occur on continents where crustal rocks are metamorphosed by invading, hot fluids associated with igneous intrusions. 3. Burial …

WebMetamorphism. fundamental changes in the texture, structure, and mineral and chemical composition of rocks in the earth’s crust and mantle owing to the effect of abyssal fluids … WebFor example, hydrothermal metamorphism occurs when hot mineral-rich fluids flow through existing rocks, altering their mineralogy and texture. Burial metamorphism occurs when rocks are buried deeply under sediment, resulting in changes to their mineralogy and texture due to the increased pressure and temperature.
