“…In the field and in thin sections the schists show typical greenschist-facies metamorphic assemblage consisting of chlorite-actinolite-sericite/white mica-quartz ± plagioclase. In general, the greenschist-facies metamorphic grade and deformational features of the schists underlying the Aliki Limestones are undistinguishable from the metamorphic, structural and deformational pattern recorded in the same schists of the metavolcano-sedimentary series exposed in the west (Bonev and Stampfli, 2011).…”

“…3). Both units occur as distinct inliers below Cenozoic cover sedimentary and volcanic successions, or they form tectonic slices juxtaposed through thrust and extensional faults against the Rhodope high-grade metamorphic basement units (Bonev and Beccaletto, 2007;Bonev et al, 2010a, b;Bonev and Stampfli, 2011).…”

“…Recently Bonev and Stampfli (2011) identified two fold generations as the penetrative second generation is associated with fold hinge propagating north-directed thrusts. The deformational pattern of Makri unit, in continuum with the whole eastern Circum-Rhodope Belt, was interpreted as a result from Late Jurassic north-directed thrust emplacement of this belt onto the Rhodope continental margin, with a pronounced subsequent tectonic reworking during the Cenozoic crustal extension (Bonev and Stampfli, 2011, and references therein).…”

“…The foliation is intensely folded into northwest-vergent tight to sub-isoclinal folds that represent parasitic, subordinate small-scale folds in the eastern closure of a large-scale antiform within the Makri unit cored by the metasedimentary series in the west (e.g. Papadopoulos, 1980;Bonev and Stampfli, 2011). In the field and in thin sections the schists show typical greenschist-facies metamorphic assemblage consisting of chlorite-actinolite-sericite/white mica-quartz ± plagioclase.…”

“…Dercourt et al (2000), Stampfli & Borel (2002), Gaetani et al (2003) showed a small scale, global plate-tectonic model for the Paleozoic and Mesozoic where terranes larger than the Tisza units were only indicated or united with other unit(s). On similar scale maps Bonev & Stampfli (2003, 2011 indicated microplates and even nappe sets on their paleotectonic models for the Middle and Late Jurassic and Cretaceous intervals, where the Tisza (named incorrectly Tisia) microplate was situated west of the Austro-Alpine units. The Western Carpathians are indicated on the eastern side of the AustroAlpine units.…”

Abstract:The Upper Triassic-Lower Cretaceous successions of the Transdanubian part of the Mecsek and Villány-Bihor Zones of the Tisza Unit have been studied from the lithological, lithostratigraphical, sedimentological, microfossil and microfacies points of view in order to correlate and interpret the significant differences between them and to draw a conclusion about their geological and paleogeographical history. After an overview of the paleogeographical reconstructions of the broader area, the succession of the Mecsek and Villány-Bihor Zones and the debated Máriakéménd-Bár Range are introduced. Until the end of the Middle Triassic the study area acted as an entity. The first fundamental difference between the two zones can be recognized in the Late Triassic when marine carbonates were replaced by thick fluvial siliciclastics in the Mecsek Zone, while it is represented only by small, local lenses with a few and thin dolostone intercalations in the Villány Zone. The Mecsek Zone is bordered southward by one of the large listric faults to the north of which very thick siliciclastics developed in the Early to Middle Jurassic, whereas it is highly lacunose in the larger western part of the Villány-Bihor Zone. The break at the base is subaerial, higher in the succession it is shallow submarine. The sediment is silty, occasionally sandy crinoidal limestone of late Early Jurassic or even Middle Jurassic in age. The Upper Jurassic in the Mecsek Zone is composed of deep-water cherty limestone while in the Villány Zone it became a thick, shallowing pelagic limestone with reworked patch reef fragments. It is clear evidence that the Mecsek Zone had a thinned continental crust thanks to the nearby rift zone while in the Villány Zone the crust remained thick. The actualized version of the Plašienka's paleogeographical model (Plašienka 2000) is introduced.

Tectonic, magmatic, and metallogenic evolution of the Late Cretaceous arc in the Carpathian‐Balkan orogen

et al. 2015

The Apuseni-Banat-Timok-Srednogorie Late Cretaceous magmatic arc in the Carpathian-Balkan orogen formed on the European margin during closure of the Neotethys Ocean. It was subsequently deformed into a complex orocline by continental collisions. The Cu-Au mineralized arc consists of geologically distinct segments: the Apuseni, Banat, Timok, Panagyurishte, and Eastern Srednogorie segments. New U-Pb zircon ages and geochemical whole rock data for the Banat and Apuseni segments are combined with previously published data to reconstruct the original arc geometry and better constrain its tectonic evolution. Trace element and isotopic signatures of the arc magmas indicate a subduction-enriched source in all segments and variable contamination by continental crust. The magmatic arc was active for 25 Myr (~92-67 Ma). Across-arc age trends of progressively younger ages toward the inferred paleo-trench indicate gradual steepening of the subducting slab away from the upper plate European margin. This leads to asthenospheric corner flow in the overriding plate, which is recorded by decreasing Nd (0.51234 to 0.51264) ratios over time in some segments. The close spatial relationship between arc magmatism, large-scale shear zones, and related strike-slip sedimentary basins in the Timok and Pangyurishte segments indicates mild transtension in these central segments of the restored arc. In contrast, the Eastern Srednogorie segment underwent strong orthogonal intraarc extension. Segmental distribution of tectonic stress may account for the concentration of rich porphyry Cu deposits in the transtensional segments, where lower crustal magma storage and fractionation favored the evolution of volatile-rich magmas.
