“…In the Pontides, predominant volcanic rocks were mostly emplaced between the late Turonian and latest Campanian (~90-70 Ma) (figure 5) and seem to display southward migration through time [Yılmaz et al, 1997;Bektaş et al, 1999;Okay et al, 2001b;Eyüboğlu et al, 2010], similar to magmatic products in the Balkans [Ciobanu et al, 2002;von Quadt et al, 2005;Kolb et al, 2012].…”

“…Behind this compressional front, transtensional to extensional tectonics allowed the opening of sedimentary basins [Willingshofer et al, 1999;Sunal and Tüysüz, 2002]. At the same time, the magmatic activity seems to migrate southward [Yılmaz et al, 1997;Ciobanu et al, 2002;von Quadt et al, 2005;Eyüboğlu et al, 2010] suggesting a southward retreat of the oceanic slab Kolb et al, 2012]. Further north, the opening of the Black Sea basin was associated with an intense stretching of the crust and oceanic spreading in Cenomanian to Santonian times [Zonenshain and Le Pichon, 1986;Görür, 1988;Hippolyte et al, 2010;Nikishin et al, 2015b].…”

“…Major ore deposits within the ABCD are mostly related to calc-alkaline magmatism, which was associated with transitional subduction-collision processes followed by extension during the Late Cretaceous and Oligocene to Neogene periods. Late Cretaceous magmatism/volcanism dominates mostly in the eastern part of the ABCD metallogenic belt, often denoted as the Banatitic Magmatic and Metallogenetic Belt (BMMB -Berza et al 1998;Ciobanu et al 2002 and citation therein) or Apuseni-Banat-Timok-Srednogorie belt (ABTS -Popov & Popov 2000;von Quadt et al 2005 and citation therein) occurred in Romania, Serbia and Bulgaria. Although granitic rocks -"banatites" and their characteristics are similar within this belt, there are mutual differences in type of mineralization, for example, the porphyry-type Cu± Au± Mo deposits, associated epithermal massive sulphides, and Fe-Cu skarn.…”

“…The Late Cretaceous ore-bearing magmatism lasted over 25 Ma (from ca. 92 to 65 Ma) and more than 50 important deposits and occurrences are genetically and spatially associated with "banatites" (see reviews: Ciobanu et al 2002;von Quadt et al 2005;Zimmerman et al 2008). However, Late Cretaceous magmatism is scarce within the western part of the ABCD belt where only minor aplite and pegmatite veins are reported to accompany Cretaceous metamorphism in the Alps and mineral deposits contrast with contemporaneous metamorphogenic siderite/ magnesite/talc and hydrothermal Cu vein deposits exposed in the Eastern Alps and Western Carpathians (Neubauer 2002).…”

The subsurface Rochovce granite intrusion was emplaced into the contact zone between two principal tectonic units (the Veporic Unit and the Gemeric Unit) of the Central Western Carpathians (CWC), Slovakia. The Cretaceous age of this granite and its Mo-W mineralization is shown using two independent methods: U-Pb on zircon and Re-Os on molybdenite. The studied zircons have a typical homogeneous character with oscillatory zoning and scarce restite cores. SHRIMP U-Pb data provide an age of 81.5 ± 0.7 Ma, whereas restite cores suggest a latest Neoproterozoic-Ediacaran age (~565 Ma) source. Zircon εHf(81) values -5.2 to + 0.2 suggest a lower crustal source, whereas one from the Neoproterozoic core εHf(565)= + 7.4 call for the mantle influenced old precursor. Two molybdenite- bearing samples of very different character affirm a genetic relation between W-Mo mineralization and the Rochovce granite. One sample, a quartz-molybdenite vein from the exocontact (altered quartz-sericite schist of the Ochtiná Formation), provides a Re-Os age of 81.4 ± 0.3 Ma. The second molybdenite occurs as 1-2 mm disseminations in finegrained granite, and provides an age of 81.6 ± 0.3 Ma. Both Re-Os ages are identical within their 2-sigma analytical uncertainty and suggest rapid exhumation as a consequence of post-collisional, orogen-parallel extension and unroofing. The Rochovce granite represents the northernmost occurrence of Cretaceous calc-alkaline magmatism with Mo-W mineralization associated with the Alpine-Balkan-Carpathian-Dinaride metallogenic belt.

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.
