Geothermal metamorphism
Web-Geothermal Gradient: metamorphism occurs in different settings that have different characteristics of heal flow, differential stress, and hydrothermal fluid interaction.-Metamorphism: all changes in mineralogy and rock texture. As a result of changes in temperature and pressure. WebMetamorphism results from a complex interplay between physical and chemical processes that operate on a scale ranging from micrometres (e.g., fine mineral grain sizes, thickness of intergranular fluid, diffusion …
