Hydrothermal mineral deposits are accumulations of valuable minerals which formed from hot waters circulating in Earth's crust through fractures. They eventually produce metallic -rich fluids concentrated in a selected volume of rock, which become supersaturated and then precipitate ore minerals.

The Oubasi orogenic gold deposit in Southern Ghana is host to mineral resources of over 70 Moz Au at a grade of 7.39g/t or higher, with a past production of 32 Moz Au. [9] The deposit is located in the Birimian orogen, where gold mining is known to have taken place back to the 17th century, but modern industrial-scale mining began in 1897 by ...
Volcanogenic massive sulfide ore deposits, also known as VMS ore deposits, are a type of metal sulfide ore deposit, mainly copper-zinc which are associated with and produced by volcanic-associated hydrothermal events in submarine environments. [2] [3] [4] These deposits are also sometimes called volcanic-hosted massive sulfide (VHMS) deposits
Epithermal — mineral ore deposits formed at low temperatures (50–200 °C) near the Earth's surface (<1500 m), that fill veins, breccias, and stockworks. [2] Telethermal — mineral ore deposits formed at shallow depth and relatively low temperatures, with little or no wall-rock alteration, presumably far from the source of hydrothermal ...
The term "polymetallic ore" also includes nodules, principally Manganese nodules, that do not form as terrestrial deposits but as concretions on the ocean floor. [ 3 ] [ 4 ] Rocks containing polymetallic ores are often altered or formed by hydrothermal processes — chloritization , sericitization and silicification .
There are a few foods you may want to skip on Thanksgiving if you're taking a GLP-1 medication such as Ozempic, dietician Kylie Bensley, founder of the women’s nutrition company, Sulinu, tells ...
SEDEX deposits belong to the large class of non-magmatic hydrothermal ore deposits formed by basinal brines. [11] This class includes also: Mississippi valley type (MVT) zinc-lead deposits. [8] Sediment-hosted stratiform Cu-Co-(Ag) deposit, typified by the Copperbelt of Zambia and DRC. [12]
