Abstract :The paper deals with the Middle Palaeozoic oceanic events on the northern margin of the Eastern Mediterranean Hercynides. The Balkan-Carpathian Ophiolite Belt insert ignore into journalissuearticles values(BCO); and palaeo-oceanic zones of the Great Caucasus, all framing the East European Platform from the south, are correlated. The BCO palaeo-oceanic complex was widely thought to be a Late Precambrian-earliest Cambrian oceanic thrust sheet insert ignore into journalissuearticles values(563±5 Ma);, a part of the South European Palaeo-oceanic Suture. The geochronological studies carried out on gabbroic series of the Deli Jovan Massif insert ignore into journalissuearticles values(BCO, NE Serbia);, showed, however, that they are of much younger insert ignore into journalissuearticles values(Early Devonian); age: insert ignore into journalissuearticles values(a); Sm-Nd mineral isochron age of 406±24 Ma, eNdT= 8.32±0.39; 87Sr/86Srinit= 0.702592±0.000160; and insert ignore into journalissuearticles values(b); U-Pb SHRIMP zircon age, 405.0±2.6 Ma. All the studied gabbroic rocks represent high-alumina insert ignore into journalissuearticles values(19-24.5% Al2O3); gabbro-troctolites, originating from shallow level insert ignore into journalissuearticles values(
