Les minéralisations cuprifères supergènes (MCS) représentent la viabilité économique de nombreux porphyres cuprifères de par le monde. Ces minéralisations dérivent de processus supergènes, définis comme étant l'altération en conditions oxydantes des sulfures primaires et tout enrichissement en sulfures secondaires qui en découle. Des conditions tectoniques, climatiques et géomorphologiques favorables sont requises pour la formation des minéralisations cuprifères supergènes. La tectonique contrôle le soulèvement nécessaire pour induire la baisse de la nappe phréatique et l'oxydation des sulfures primaires. Le climat contrôle le lessivage du cuivre dans l'environnement supergène et la circulation des eaux météoriques dans le milieu de dépôt. ...
