The formerly distinguished Serbian-Macedonian Massif has been divided by Popovic (1990b and 1991) in to two geotectonical blocks: the Pelagonian-Rhodopean and the Morava massifs. The second one, including the Green and the Gneiss complexes, mostly occurs in Serbia. It is supposed that the first block originated in the oceanic area during the Baikalian stage (this opinion being supported by paleontological records), whereas the gneisses are assumed to originate in the continental crust, during the same stage of the Baikalian tectonic-magmatic cycle. The Baikalian matallogenic epoch in the green complex is featured by the Fe, Ti, S, Cu, Cr, Zn and Au occurrences, being particularly characterized by copper sulfides and gold. It is supposed that two constituents could play an important role in the future investigations. It has been presumed that this metallogenic epoch is related to the small iron deposits (Žitni Potok, Desivojce, Sedlare, Car and other), which appear in the gneiss complex. The Calledonian metallogenic epoch is especially characterized by copper sulfides, graphite occurrences and phosphate deposits, as well as by the iron deposits of the silicate-carbonate type and also by the manganese, nickel and cobalt occurrences. Finally, the Hercynian metallogenic epoch is known by the continental regime producing the coal and uranium deposits in sediments and granitoids, as well as the beryllium occurrences in pegmatites.
