| Abstract | This chapter on metamorphosed hydrothermal ore deposits summarizes key attributes of mineral deposits that are hydrothermal in nature, originally formed at shallow crustal depths, entrained in
orogenesis, metamorphosed to the upper amphibolite or granulite facies, and preserved. Due to the significant mineralogical, textural, and structural changes associated with metamorphism, such ore systems are commonly camouflaged within their highly
deformed and metamorphosed host setting. Nevertheless, the well-documented geochemical and mineralogical signatures and geospatial patterns of alteration zones associated with hydrothermal ore deposits remain diagnostic once metamorphosed. Knowledge
of their systematic mineralogical and paragenetic characteristics enhances their identification and may optimize lithogeochemical exploration programs in high-grade metamorphic terranes. With time, this will facilitate discoveries of ores, improve
metamorphosed ore deposit models, and further stimulate the development of exploration guidelines for their underexplored host terranes. |
