“…Three tectonic scenarios, aiming to explain this feature, have been proposed: (1) Stampfli and Borel () suggested that in the Silurian the Gondwanan northern margin was active and the syn‐Caledonian magmatic arc developed along the future Cadomian terranes. This model is accepted in many studies (e.g., Balintoni & Balica, ; Neubauer, ; Reischmann & Anthes, ; Stampfli et al, ; von Raumer et al, ); (2) Caledonian‐aged magmatism reflects accretion of a first train of the Cadomian (Hun) terranes that left Gondwana at the same time as Avalonia (versus the Galatian terranes that remained connected then to Gondwana; Stampfli et al, ); and (3) the peri‐Gondwanan microplates, accreted to the Laurussian margin, comprised mostly Avalonian but also occasional Cadomian‐type crustal fragments (Zlatkin et al, ; Figure ).…”

“…Tectonics peri-Amazonian Avalonian terranes were docked at the northern periphery of the West African craton in the Middle Cambrian (ca. 530 Ma; e.g., Barr et al, 2012;Domeier, 2016;Keppie & Keppie, 2014;Landing, 2005;Zlatkin et al, 2017).…”

“…Its zircon age spectra, dominated by detrital zircon ages of 1.0-2.0 Ga (main peak at 1.5 Ga), show a peri-Amazonian affinity. The Proto-Pelagonian rock unit is intruded by Neoproterozoic (700 and 600-Ma) granitoids with Avalonian model ages of 1.0-1.4 Ga (Zlatkin et al, 2014) and overstepped by a Late Ediacaran-earliest Cambrian (570-530-Ma) Avalonian succession, the zircon age spectra of which is concentrating mainly at the 750-560-Ma interval and display an inherited isotopic signature from the underlying Avalonian granites (Zlatkin et al, 2017). The Pelagonian terrane hosts no Caledonian record but hosts widespread Variscan granites (Anders et al, 2006(Anders et al, , 2007Mountrakis, 1984;Pe-Piper et al, 1993;Reischmann et al, 2001;Schenker et al, 2014;Yarwood & Aftalion, 1976;Zlatkin et al, 2017).…”

Between the eastern Mediterranean basin in the South and the East European (Baltica) Craton to the north, we distinguish two fundamental pre‐Variscan geological domains: an Internal domain, which hosts Ordovician‐Devonian (450–400 Ma) igneous rocks and detrital zircon populations, and an External domain, which contains no 450‐ to 400‐Ma zircon ages. From the Balkan Peninsula to the Turkish plate, the aforementioned Internal domain includes the Serbo‐Macedonian Massif, the Istanbul and Sakarya terranes, whereas the External domain, holding a more distal position relative to Baltica, includes the Pelagonian terrane and the External Hellenides. The two domains are interpreted as two consecutive (i.e., Caledonian and Variscan) Paleozoic accretionary belts, attached to the southern margin of Baltica. The Cycladic and Pelagonian terranes are currently juxtaposed along strike of the central Hellenides in Northern Greece. The Cycladic Massif is a Cadomian‐type terrane, while the Pelagonian displays an Avalonian‐type affinity. Despite its Avalonian affinity, the Pelagonian lacks Ordovician‐Devonian (450–400‐Ma) zircon ages. In contrast, detrital zircon grains of such ages are abundant in the Cycladic Massif. In this study, the Ordovician‐Devonian detrital zircon population is recognized also in pre‐Variscan (>310‐Ma) Cycladic Basement from Ios and Naxos Islands, affiliating the Cycladic Massif with the Internal (Caledonian) domain. This indicates that the Caledonian accretion incorporated some Cadomian‐type terranes. It also suggests that the protolith of the Cycladic blueschists was deposited within the Internal domain, that is, northeast of the Pelagonian terrane. This recognition helps to reconstruct the Paleozoic and Mesozoic paleogeography of the peri‐Gondwanan terranes.

“…the Moesian microplate. Outlying the Moesian accretionary configuration, separated by the Vardar-Axios Zone it appears that the lattermost fartravelled Avalonian-Amazonian fragment (ZLATKIN et al, 2014;ZLATKIN et al, 2017) incorporated within SEE is the Pelagonic Massif. Together with the DIE, these two pre-Variscan systems embody the Alpine basement of the prominent Dinarides-Hellenides orogen, positioned in the very center of the late Mesozoic Alpine suture referred to as the Vardar Zone (e.g., DIMITRIJEVIĆ, 1999;ZELIĆ et al, 2010;SACCANI et al, 2011 and references therein;SCHENKER et al, 2015).…”

This paper addresses a Drina-Ivanjica basement member, Drina Formation, characterized by ŕ controversial Neoproterozoic to Carboniferous age. The Drina Formation is also informally referred to as the "Lower Drina Formation" and the "Upper Drina Formation" including the Golija Formation as a conditional analog unit of the latter. A review of the biostratigraphic, sedimentary and paleogeographic constraints identified Drina Formation (Inner Dinarides) as a migrated crustal segment derived from a marginal section of northern Gondwana, being, however, of Neoproterozoic-Early Paleozoic age.The presence of arenites, pelites, conglomerates, scarce limestones, basic (sub)volcanics and tuffs of the volcano-sedimentary Drina Formation metamorphosed up to greenschist and locally up to amphibolite facies, coupled with the absence of felsic volcanism implies a passive margin setting. Considering the age, such environment was probably associated with the perplexed Lower Paleozoic Avalonian-Cadomian arc, situated along the former north Gondwanan active margin. More precisely, the Drina Formation originated from a depositional junction between the Gondwana sediment supplier (Sahara metacraton) and Cadomian arc. A comparison with the regional Early Paleozoic succession of the "Kučaj Unit" (eastern Serbia) yields the absence of typical anchimetamorphic Silurian to Lower Devonian deep-marine fossil-bearing succession. The volcano-sedimentary passive margin system of Drina Formation is overlain by a late Variscan convergencerelated voluminous clastic sequence allocated as the Golija Formation.Апстракт. Фокус овог рада је Дринска формација, део Дринско-ивањичког бејсмента контроверзне неопротерозојско-карбонске старости. Корелацијом биостратиграфских, палеогеографских и геодинамичких података изведени су закључци о неопротерозојско-ранопалеозојској старости Дринске формације, као дела некадашње северногондванске маргине.Присуство аренита, пелита, конгломерата, базичних (суб)вулканита и туфова као доминантних литотипова Дринске формације (уз нешто карбоната), метаморфисаних претежно у фацији зелених шкриљаца, а локално и у амфиболитској фацији, маркира сложене тектонске догађаје маргиналног дела северне Гондване. Средина настанка Дринске формације је вероватно била позиционирана између главне области ерозије тј. сахарског кратона и ободног кадомског лука (гондвански систем континенталних и вулканских лукова). Упоредном анализом са регионално метаморфисаном доњопалеозојском сукцесијом "Кучајске јединице" (источна Србија) уочава се одсуство (средње-и горњо-)ордовицијумских, силурских и доњодевонских творевина у метаморфитима Дринске формације, што упућује на највероватнији доњи ордовицијум као терминални период формирања протолита. Присуство измењених базичних стена, са друге стране, указује на реликте неопротерозојско -доњопалеозојског вулканогено-седиментног лучног система. Махом кластична доњокарбонска повлатна сукцесија тзв. Голијске формације маркира касноварисцијску (највероватније конвергентну) фазу развоја овог тектонски одвојен...
