Sažetak
In the Central Dinarides and South Tisia different Paleozoic complexes occur in four geotectonic zones: 1) comparatively autochthonous units located in the cores of disrupted anticlines of the External Dinarides ; 2) allochthonous disrupted units accompanied by more predominant Triassic formations in the Sava nappe which is thrust onto the northeastern margin of the External Dinarides ; 3) allochthonous disrupted units, also together with Triassic formations, in the Pannonian and Durmitor nappes of the Internal Dinarides ; and 4) polymetamorphic sequences in basement of the Pannonian Basin and South Tisia, respectively. This paper presents basic geological and metallogenic features for the main Paleozoic areas included in these four zones. The Paleozoic complexes of the first two zones were related to the Gondwana passive continental margin, and they can be correlated with the ones from the Southern Alps. Those of the third zone were related to the Paleotethyan oceanic realm, and can be correlated with the Austroalpine units. The Tisia Paleozoic complexes were related to the active Laurussia margin. Geodynamic evolution of all these Paleozoic complexes was related to the opening and closure of Rheic and Paleotethys oceans. Rifting processes along North Gondwana started in the Silurian, locally in the Cambrian-Ordovician, followed by the Late Silurian/Devonian opening of the Paleotethys. Subduction processes were active by the end of the Devonian and at the beginning of the Carboniferous along the Laurussia margin. They were followed during the Namuriif4n-Westphalian by main Variscan deformation during collision of Gondwana and Laurussia. Associated metamorphism was very low-grade in the Paleozoic units of the Sava nappe, very low and low-grade, locally to epidote-amphibolite grade within the Paleozoic complexes of the Pannonian and Durmitor nappes in the Internal Dinarides, and polymetamorphic with migmatites and granitoids in South Tisia. These processes gave rise to a Pangea stage with Variscan basement disconformably overlain by Late Carboniferous and Permian sediments.
