ABSTRACT
Large lead-zinc mineralized vein swarms are associated with the Madan Dome in the Central Rhodopes, which is interpreted as a large metamorphic core complex. Within the scope of the GEODE-ABCD-project, studies in the Central Rhodopian area are carried out using high-precision geochronology to determine the relationship between and the timing of extensional detachment motion, core complex uplift, local acid magmatism and hydrothermal ore formation which should yield a p-T-t- model of the development of the Madan core complex. In conjunction with isotopic tracer and fluid inclusion data, we hope to identify the sources of ore-forming components and the mechanism of hydrothermal metal transport and precipitation.
