Abstract
VMS deposits in the Greater Antilles are described throughout the Dominican Republic and Cuba, genetically linked to two main episodes of the island-arc tectonic and magmatic evolution: 1) bimodal mafic type deposits, formed during the earliest stages of island-arc volcanism and 2) mafic (Cyprus) type, formed in mature back-arc basins (Nelson et al., 2011). Bimodal-mafic VMS deposits are in the main hosted in tholeiitic volcanic rocks of Early Cretaceous age of the Maimón and Amina Formations i...
