Cenozoic magmatism in the border area of W Bulgaria - E Macedonia - SE Serbia: temporal evolution, geochemical trends and fertility in changing compression-extension regime

The Balkan Peninsula is one of Europe's mineralized regions with world-class ore deposits. Numerous porphyry Cu-(Au-Mo) and epithermal Au-(Cu) deposits are related to Upper Cretaceous calc-alkaline magmatism formed during oblique northward subduction of the Tethys beneath the European continent and slab roll-back. The next time period with important Pb-Zn-Au-Cu mineralization is Cenozoic (mainly Oligocene) and related to post-collisional magmatism. We present here integrated U-Pb zircon, Sr-Nd-Hf isotope and geochemical analyses on Palaeogene rocks from W Bulgaria, SE Serbia and E Macedonia (FYROM) with the aim to constrain the temporal and tectonomagmatic evolution of the region that favoured significant ore-formation
