Hydrothermal fluids geology
WebIntroduction. Hydrothermal processes concern the subsurface movements of hot water. (“Thermos” means heat and “hydros” means water.) The heat is usually supplied by … Hydrothermal mineral deposits are accumulations of valuable minerals which formed from hot waters circulating in Earth's crust through fractures. They eventually create metallic-rich fluids concentrated in a selected volume of rock, which become supersaturated and then precipitate ore minerals. In some occurrences, minerals can be extracted for a profit by mining. Discovery of mineral deposits consumes considerable time and resources and only about one in every one t…
