Hydrothermal mineral deposit Wikipedia

Hydrothermal mineral deposits are accumulations of valuable minerals which formed from hot waters circulating in Earth's crust through fractures. They eventually create rich-metallic fluids concentrated in a selected volume of rock, which become supersaturated and then precipitate ore minerals.In some occurrences, minerals can be extracted at a profit by mining.
