Alteration Forming Minerals in Porphyry Copper Deposits

Hydrothermal alteration in porphyry copper deposits
Refers to metasomatic processes that change the composition, mineralogy, and texture of rocks that constitute a porphyry copper system. In porphyry environments, wall-rock alteration is intimately linked to narrow veins, commonly 0.1 to 10 cm in width, that typically make up less than 1 to 5 volume percent of ore but also are present in other alteration zones.
Hydrothermal alteration is characterized by ionic metasomatism, including alkali metasomatism and hydrolytic (or acidic) reactions, oxidation-reduction reactions (including sulfidation), solubility-induced precipitation reactions, such as quartz precipitation, and hydration-carbonation reactions in which water or carbonate is added.
Major alteration types commonly present in porphyry copper
deposits are (1) potassic, (2) sericitic, (3) advanced argillic, (4) intermediate argillic, (5) propylitic, (6) sodic-calcic and sodic, (7) greisen, and (8) skarn.

Nice! Do you deal with the external identification of the copper minerals themselves anywhere? How do you do a field ID of cuprian goethite & other surface alteration effects?

search on the list of videos "limonite in porphyry copper deposits", there are four videos on leach cap interpretation. Thank you for your participation.

Excelente Sebastian, pero si pudieras realizar tambien en castellano, seria excelente. Saludos

Claro que SI, todos los videos estan hechos en Castellano y en Ingles, eso es tambien para ayudar a las persoans que estan aprendiendo Castallano y tambien Ingles, aqui esta la version en Castellano de esa Presentacion kzbin.info/www/bejne/fmGYkqCpi7GXe9k Gracias, gracias, gracias
