Résumé(disponible en anglais seulement)
Volcanogenic massive sulphide (VMS) deposits contain variable amounts of gold, both in terms of average grade and total gold content, with some VMS deposits hosting world-class gold mines with more than 100 t Au. Various examples will be presented in order to illustrate the principal characteristics of gold-rich VMS systems, including the geologic, volcanic and geodynamic context, the hydrothermal alteration and mineralization styles, gold distribution, etc. Some key geologic and genetic parameters will be discussed in terms of potential implications for exploration in Paleoproterozoic greenstone belts
