7.5: Contact Metamorphism and Hydrothermal Processes

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.

WebJul 16, 2024 · It can occur as a halo around a range of ore deposit types and characterizes what is known as the sinter zone in high level epithermal deposits. Silicification also occurs in the majority of fractures that hydrothermal fluids have passed through, forming quartz veins. Carbonate-hosted mineral deposits have complex alteration envelopes ( MDRU) 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. ease wool yarn

Where does hydrothermal metamorphism occur?

WebA common phenomenon is the effect produced adjacent to igneous intrusions where several metamorphic zones represented by changing mineral assemblages reflect the temperature gradient from the high-temperature intrusion to the low-temperature host rocks; these zones are concentric to the intrusion. WebAug 28, 2024 · The heat that causes metamorphism naturally fuels the reactions. In contrast, retrograde reactions are mostly exothermic – they give off heat. There is no outside energy driving the reactions. • At low temperature, reactions are very sluggish; they may not have time to reach equilibrium.
