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.

2.2 Porphyry-epithermal mineral system | Geoscience Australia

Skarn deposits are also zoned in this mineral system, with Cu-rich skarns generally very close to the causative intrusion, but Zn-Pb-rich skarns more distal. An important feature of the porphyry-epithermal mineral system is the telescoping of different deposit types, for instance porphyry Cu-Au-Mo deposits and epithermal deposits of various types.

Rock and Mineral Resources | Geology

Uranium deposits are usually sourced from radioactive granites, where certain minerals such as monazite are leached during hydrothermal activity or during circulation of groundwater. The uranium is brought into solution by acidic conditions and is deposited when this acidity is neutralised. Generally this occurs in certain carbon-bearing sediments, within an unconformity in sedimentary strata.

All ore deposits are mineral deposits, but the reverse is not true. Ore deposit is an economic term, while mineral deposit is a geologic term. Whether a given mineral deposit is also an ore deposit depends on many factors other than the level of concentration and the size of the deposit; all factors that affect the mining, processing, and transporting of the ore must be considered as well.
