The nature of hydrothermal processes found from the rock record through mineralogical evidence on ore deposits was naturally supplemented by data from investigations of modern and active geothermal systems. Our initial consideration was to ascertain whether geothermal processes and hydrothermal ore genesis were related phenomena.

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 Minerals | National Museum Wales

Introduction. Wales has an abundance of hydrothermal (literally meaning 'pertaining to hot water') mineral deposits. Hydrothermal activity occurs at many levels in the Earth's crust, from deep-down (a kilometre or more) to the surface (fumarolic deposits around geysers) with hydrothermal fluids generated by igneous, metamorphic and sedimentary processes or a combination of these.

The mineral-laden water emerges from the seafloor via hydrothermal vents called black smokers, named after the dark-colored precipitates produced when the hot vent water meets cold seawater. (see Chapter 4, Igneous Rock and Volcanic Processes) Ancient black smokers were an important source of copper ore for the inhabitants of Cyprus (Cypriots ...

Commercially valuable mineral deposits are believed to exist on the seafloor near hydrothermal vents, and a few companies have had plans in development for years to exploit some of these. The difficulty of mining in deep water near fragile ecosystems and the relatively small size of ocean bottom deposits compared to those on land have so far ...

We can only proceed using "best estimates" but the versatility of hydrothermal processes gives us the flexibility to adapt the hydrothermal model as new evidence and constraints emerge. For example, Miller and Bada (1988) seized on another problem, arguing that far from being encouraged to form in black smokers, amino acids would, if in ...

But hydrothermal deposits may also form on the ocean bottom. These openings through which hot mineral-rich water enters the sea are called hydrothermal vents (black and white smokers). Hydrothermal deposits may also form subaerally in volcanically active areas. Hydrothermal mineralization is the precipitation of minerals out of the hot fluid.

Porphyry deposits. Among the most distinctive hydrothermal deposits is a class known as porphyry copper deposits, so called because they are invariably associated with igneous intrusives that are porphyritic (meaning the rock is a mixture of coarse and fine mineral grains).Porphyry copper deposits (and their close relatives, porphyry molybdenum deposits) contain disseminated mineralization ...
