Evolution and geodynamic significance of the tertiary orogenic volcanism in Northeastern Greece

Extremely Re-Rich Molybdenite from Porphyry Cu-Mo-Au Prospects in Northeastern Greece: Mode of Occurrence, Causes of Enrichment, and Implications for Gold Exploration

“…The second phase of core complex related extension in the Rhodope Massif was coeval with the accretion and subduction of a continental block composed of several microcontinents (Gavrovo-Tripolitsa, Olympos, Ionian, Apulian), and the subsequent subduction of the Mediterranean Sea [32]. Slab rollback (since about 35-30 Ma ago) is consistent with the progressive southward migration of magmatic activity from the Tertiary in the Rhodope Massif to the present in the South Aegean volcanic arc, and for the development of the Aegean subduction zone [26,27,32,36,38]. The Palaeogene magmatism of the central and eastern Rhodope Massif culminated at about 30-35 Ma and was accompanied by abundant ore-forming hydrothermal activity [31,40].…”

“…The upwelling asthenosphere provided the heat for hydrous melting of a heterogeneously enriched subcontinental mantle, resulted in the weakening of the crust, and may have produced the accelerated generation of the metamorphic core complexes in the Rhodope Massif [32,34,35]. The plutonic rocks (mostly granite to monzonite), and calc-alkaline to shoshonitic and ultra-K volcanic associations have geochemical and isotope affinities with supra-subduction rocks [31,36,37]. The second phase of core complex related extension in the Rhodope Massif was coeval with the accretion and subduction of a continental block composed of several microcontinents (Gavrovo-Tripolitsa, Olympos, Ionian, Apulian), and the subsequent subduction of the Mediterranean Sea [32].…”

The geodynamics of the Aegean and Anatolia: introduction

“…The papers in this book shed some light on various aspects of this extensional tectonics of the Aegean region, but there are still many contentious issues concerning the origin, timing and evolution of Neogene crustal extension in this broad zone of convergence between Africa and Eurasia (see Taymaz The Aegean region is also characterized by widespread post-collisional magmatism expressed by extensive volcanic sequences, hypabyssal intrusions and granitoid bodies (Fytikas et al 1976(Fytikas et al , 1984Altherr et al 1982;Bingöl et al 1982;Innocenti et al 1984Innocenti et al , 2005Güleç 1991;Seyitoǧlu et al 1992Seyitoǧlu et al , 1997Hetzel et al 1995a This introduction is aimed at presenting a synoptic overview of the regional geology and geophysics based on the existing literature, as well as outlining the results of recent literature on existing controversies about the tectonic and geodynamic evolution of the Aegean region. The geology of this region has been reviewed in a series of recent special publications, providing in-depth coverage of the extant data and models, and readers are referred to these publications for additional information (Robinson 1997;Gourgaud 1998;Bozkurt & Rowbotham 1999a, b;Durand et al 1999;Bozkurt et al 2000;Bozkurt & Mittwede 2001Aksu et al 2002Aksu et al , 2005 …”

Petrostratigraphic evolution of the Thrace Basin (Bulgaria, Greece, Turkey) within the context of Eocene-Oligocene post-collisional evolution of the Vardar-İzmir-Ankara suture zone

“…This interpretation is challenged by the lack of a coeval magmatic arc along its northern (Strandja) margin. Besides, penecontemporaneous volcanism kicked off late in the basin evolution (Caracciolo et al, , 2012d'Atri et al, 2012;Innocenti et al, 1984;Yanev, 1998;Yanev, Innocenti, Manetti, & Serri, 1998) in contrast with typical forearc basins (for a review, see Dickinson, 1995). The interpretation of the Thrace Basin as a forearc basin was also based on the occurrence, along its southern margin in the Gelibolu peninsula, of a belt of chaotic deposits long interpreted as a tectonic mélange formed in situ in an accretionary prism (Beccaletto, 2004;Beccaletto et al, 2005).…”

“…The remaining Eocene section is characterized by a general paleoenvironmental trend from shelf/slope deposits to the west to deeper-marine turbidites to the east . In the Early Oligocene, the western Thrace Basin system underwent an increasingly complex tectonic and palaeoenvironmental evolution (Innocenti et al, 1984), possibly the result of the progressive exhumation/unroofing of the Rhodopes inducing higher local erosion rates and the progradation of coarse-grained clastic wedges from the basin margins.…”
