Abstract

New data for the magmatism, hydrothermal alteration, mineralization styles, isotope geochronology, mineralogy, fluid-inclusionsand elemental geochemical associations are combined in the present study to characterize the Tran Au- Ag±W deposit in Western Bulgaria. The main features of the deposit define it as intrusion-related gold system (IRGS): its association with reduced plutons; well-defined structural control on intrusion and mineralization; diverse mineralization styles, including veins, stockworks, dissemination; wide range of gold grades; approximately coeval magmatism and mineralization at 330-333 Ma; low sulfide content; apparent correlation of Au and Bi; and the presence of СО2 in hydrothermal fluids. These characteristics are useful for further prospecting for IRGS in the Variscan Belt of Eastern Europe.
