Hydrothermal processes of ore formation
WebHydrothermal alteration is a geological process that occurs when hot, mineral-rich fluids interact with rocks and minerals, changing their physical and chemical properties. This interaction can lead to the formation of new minerals and the alteration of existing minerals, which can result in the formation of mineral deposits, including those containing metals … Web13 feb. 2016 · Formation of Mineral Deposits Endogenous Processes • Magmatic concentration • Metamorphism/Metasomatis m • Hydrothermal process Exogenous Processes • Weathering & Supergene e nrichment • Chemical deposition • Mechanical concentration Author: melosa Post on 13-Feb-2016 193 views Category: Documents 4 …

WebExtraction and Processing Industries 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 … WebFerromanganese nodules/crusts and seafloor massive sulfides are a unique feature of the deep-ocean seafloor. These deep-ocean mineral deposits are windows into Earth's processes, revealing clues to the evolution of seawater and ancient ore-forming processes. They also represent significant metal resources that could contribute future …
