Hydrothermal mineral deposit - Wikipedia

A mineral ore deposit is the volume of rock that can be mined at a profit. Therefore, there are many variants that can define whether a mineral deposit is profitable or not, such as price, tonnage, or location. Mineral commodities can be classified as metals or non-metals. Metals refer to elements of the periodic table which include base, ferrous, minor fissionable and precious metals. On the other hand, non-metals refer to industrial minerals such as gypsum, diamonds, oil, coal and aggregate. Hydrothermal deposits of eco

Hydrothermal mineral deposit | geology | Britannica

Hydrothermal mineral deposit, any concentration of metallic minerals formed by the precipitation of solids from hot mineral-laden water (hydrothermal solution).The solutions are thought to arise in most cases from the action of deeply circulating water heated by magma. Other sources of heating that may be involved include energy released by radioactive decay or by faulting of the Earth’s crust.

HYDROTHERMAL ORE DEPOSITS

HYDROTHERMAL ORE DEPOSITS TYPES OF ORE DEPOSIT 1. Ores formed by hydrothermal processes 2. Ores formed by igneous processes within the earth 3. Ores formed by sedimentary processes at the Earth’s surface A hydrothermal fluid = a hot, aqueous fluid containing dissolved metals in solution. A mineral vein is formed when minerals precipitate in a fracture.
