“…In contrast to the MHT, at least the studied part of the Greek THB, including the Paleogene deposits of the Axios Basin, evolved as a Paleogene supra detachment basin above the strongly stretched, during the Eocene-Oligocene, Internal Hellenides ( Figures 15 and 16) [33,49]. Exhumation of deep crustal levels took place about simultaneously with basin subsidence and migration of deformation towards W-SW, as well as with the progressive change of the tectonic conditions from ductile to brittle during the Paleogene -Neogene [35,49]. The origin of the Upper Eocene-Oligocene syndepositional magmatic activity could be attributed to the subduction processes evolved during the Paleogene more further to the W-SW in Pindos or Axios ocean(s).…”

“…We interpret the Paleogene part of the THB in the NE Greek mainland as a supradetachment basin [35], as it is shown by the syntectonic deposition of the Paleogene molassic strata of the THB on the fault planes of the extensional detachment faults, related to the stretching and progressive exhumation of the Rhodope metamorphic nappe pile during the Tertiary (Figure 15) [33,35,43,[46][47][48][49]. The Paleogene volcano sedimentary infilling of the Axios Basin is regarded as equivalent to the Greek Thrace Basin sedimentary sequence.…”

“…It can be recorded in five progressive tectonic events (D1 to D5) from Eocene to Quaternary time (Figure 12). Subhorizontal extension dominates during the overall deformational history [35]. The direct stress inversion σ1 σ2 σ3 D1 is characterized by low angle normal detachment faults, recognized at the tectonic boundaries of the Paleogene basin formation with the basement rocks, where no reworking took place due to younger tectonic events (Figures 11a-11c and 12-14).…”

Based on structural analysis and lithostratigraphic data, as well as geological mapping, the Paleogene part of the Thrace Basin (THB) in NE Greece (including the Paleogene deposits of the Axios Basin, AXB) was compared with the Mesohellenic Trough (MHT) in NW Greece. Both basins are characterized by a thick sedimentary sequence of molassic-type strata (3-5 km thickness) of Tertiary age, overlain unconformably by Miocene-Pliocene and Quaternary deposits. Molassic sedimentation started almost simultaneously in both areas during the Mid-Late Eocene but it finished in different time, in the Mid-Late Miocene for the MHT and the Late Oligocene for the THB, respectively. Sedimentation in THB was also linked with an important calc-alkaline and locally shoshonitic, acid to andesitic magmatism of EoceneOligocene age. We interpreted the MHT as a polyhistory strike-slip and piggy-back basin, above the westwardemplacing Neotethyan ophiolites and Pelagonian units on the cold Hellenic accretionary prism. In contrast to the MHT, the studied portion of the THB evolved as a Paleogene supra-detachment basin above the strongly extended during the Eocene-Oligocene Rhodope metamorphic province. The syn-depositional magmatic products, linked possibly with subduction processes in Pindos or Axios ocean(s). In any case, MHT and THB are related to inferred oblique convergence of the Apulia plate and the internal Hellenic units.

Age and composition of meta‐ophiolite from the Rhodope Middle Allochthon (Satovcha, Bulgaria): A test for the maximum‐allochthony hypothesis of the Hellenides

et al. 2014

The metamorphosed thrust stack of the Rhodopes comprises a level with ophiolites (Middle Allochthon) underlain and overlain by continent-derived allochthons. The Upper Allochthon represents the European margin, but the origin of the Lower Allochthon remains controversial, with suggestions that it may be derived from an inferred microcontinent (Drama) or from the margin of Adria. Trace element compositions and Sr and Nd isotope ratios of metagabbroic amphibolites and enclosed meta-plagiogranites from the Satovcha Ophiolite, Middle Allochthon, show that they are cogenetic and represent suprasubduction zone ophiolites. U-Pb dating using laser ablation sector field inductively coupled plasma mass spectrometry of zircons from two meta-plagiogranites and a metagabbro yielded identical Jurassic ages (160 ± 1 Ma, 160.6 ± 1.8 Ma, and 160 ± 1 Ma, respectively), similar to ophiolites in the eastern Vardar Zone bordering the Rhodopes to the SW. The trace element patterns also closely resemble those of the Vardar ophiolites. The association with Late Jurassic arc-type granitoids is another feature that applies both to eastern Vardar and Satovcha. This strongly suggests that the Middle Allochthon comprises the metamorphosed northeastward continuation of the Vardar Zone. The Jurassic age of the Satovcha Ophiolite contradicts the hypothesis of Early Jurassic suturing between Europe (Upper Allochthon) and the assumed Drama microcontinent (Lower Allochthon) but is in line with the "maximum allochthony hypothesis," i.e., the assumption that the Lower Allochthon represents Adria and that the "root" of the Vardar-derived thrust sheets is at the NE boundary of the Rhodopes.

We present an integrated study of subsurface and surficial karst landforms to unravel the uplift history of karst landscape in a tectonically‐active area. To this end, we apply a multidisciplinary approach by combining cave geomorphology and Th/U dating of speleothems with remote sensing plus geophysical imaging of surface landforms. We use as an example Mt. Menikio in northern Greece where four caves share well‐defined epiphreatic/shallow phreatic characteristics that are related to the distribution of surface and buried doline fields and provide evidence for three distinct water table stillstands (e.g. expressed as cave levels) now lying at ~130 m, ~800 m and ~1600 m a.m.s.l. Our dating constraints delimit the age of the lower water table stillstand prior to 77 ka ago and imply a maximum rate of relative base level drop of 0.45 mma‐1, which is consistent with relative tectonic uplift rate estimates along currently active normal faults. We interpret the elevation of the higher water table stillstands to reflect earlier phases of uplift related to the regional tectonic events associated with the development of the North Anatolian Fault and the Northern Aegean area. Our analysis shows that the combined study of epiphreatic/shallow phreatic caves and surficial karst landforms together, is a robust way to investigate the uplift history of a karst landscape in a tectonically‐active setting. © 2019 John Wiley & Sons, Ltd.
