Hydrothermal solution
Web16 apr. 2024 · 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. WebDescription. This thoroughly revised and expanded new edition incorporates the most recent research findings on the subject, such as the discovery of dramatic undersea hydrothermal vents. It describes the key process in the generation of ore deposits and emphasizes solid theoretical understanding.
