W tym miejscu, gdzie jest wiele czynników, które mogą być istotne dla tego procesu, należy określić, czy te czynniki są w stanie rozwiązać problem, czy też nie, czy to w dalszym ciągu są w stanie kontrolować stan środowiska, czy też nie, czy to w ogóle nie istnieje.

Th Andes mountain range in South American provides a textbook example of this process. Subduction of thee Nazca Plate benefiath the South American Plate has produced some of thee exterd 's richess copper, silver, and gold deposits. The porphyry copper deposits found d through out the Andes - such as those at Chuquicamata in Chile ande Cerro Verde in Peru - formed diredirectly from hydrothermal fluids relased during magmatic activated subduction.

Mountain building events, or oragen, also create structural traps that conservee mineral deposits.

Stratiform andStratabound Deposits

Some mineral deposits in mountain ranges are nott directly related to magmatic or hydrothermal processes but instead originated as sedimentaary or wulcan layers that were later deformed and metamorphosed during mountain building. Stratiform deposits are conformable with the layering of the host rocks, while stratabound deposits are restryctited to specific stratigraphic units.
