AB The «La Pava» Au-Cu deposit is hosted by a vulcanosedimentary sequence, named Ocú Formation,developed in an island arc environment that resulted from the subduction of the Nazca Plate beneath theCaribbean Plate during the Cretaceous times. The deposit consists of disseminations and stockworks ofpyrite and chalcopyrite accompanied by barite, quartz and carbonates. Three hydrothermal alterationzones have been recognized: silicic, argillic and propilityc, typical of gold-related high sulfidation systems.A supergenic alteration overprints the hydrothermal alterations developing a cap rich in silica and Feoxides.The detailed study of the Ocú Fm. indicates that the sulfides and the accompanying gold wasformed in a submarine environment. Therefore we suggest that «La Pava» represents an Au-Cu hybriddeposit between high sulphidation epithermal and VMS types, which are found in volcanogenic massivesulphide environments
