The Neoproterozoic–Paleozoic basement in the Alpidic Supragetic/Kučaj units of eastern Serbia: a continuation of the Rheic Ocean?

This paper attempts to allocate a segment of the Paleozoic Ocean situated in what is now Southeastern Europe (SEE) into regional geological and paleotectonic synthesis connecting sedimentary, metamorphic igneous records associated with ocean’s cycle. The Supragetic basement (external section Carpatho-Balkan arch) represents tectonically reworked vestige Neoproterozoic–Lower oceanic floor system recrystallized under low temperature greenschist-facies conditions. constraints this low-grade are integrated information from overlying Silurian, Devonian Lower Carboniferous cap-rocks “Kucaj Unit” demonstrate presence major ocean crossing SEE. In connection north Gondwanan Pan-African processes, (including its cover) complex relationship occasionally anchimetamorphic Devonian, deep-water record polymetamorphic Unit”.

Unlike many high-pressure rocks characterizing Central European Variscides, SEE zone described here has only mild overprint.
