“…The Serbo-Macedonian Massif (SMM) in Greece is represented by the Vertiskos Unit that is composed of the following: (i) a sequence of migmatites, gneisses, schists, and thin marble intercalations, and (ii) a sequence of metagabbros, metadiabases, and amphibolites, intercalated with gneisses [17,[21][22][23][24]. Mafic to ultramafic rocks which belong to the Melidonis (1968) and Markoulis (1970).…”

The Vathi porphyry Cu-Au ± Mo mineralization is located in the Serbo-Macedonian metallogenic province of the Western Tethyan Metallogenic Belt. It is mainly hosted by a latite and is genetically associated with a quartz monzonite intrusion, which intruded the basement rocks of the Vertiskos Unit and the latite, 18 to 17 Ma ago. A phreatic breccia crosscuts the latite. The quartz monzonite was affected by potassic alteration, whereas the latite was subjected to local propylitic alteration. Both styles of alteration were subsequently overprinted by intense sericitic alteration. M-type and A-type veins are spatially associated with potassic alteration, whereas D-type veins are related to the sericitic alteration. Three ore assemblages are associated with the porphyry stage: (1) pyrite + chalcopyrite + bornite + molybdenite + magnetite associated with potassic alteration; (2) pyrite + chalcopyrite related to propylitic alteration; and (3) pyrite + chalcopyrite + native gold ± tetradymite associated with sericitic alteration. A fourth assemblage consisting of sphalerite + galena + arsenopyrite + pyrrhotite + pyrite ± stibnite ± tennantite is related to an epithermal overprint. Fluid inclusion data indicate that the A-type veins and related porphyry-style mineralization formed at 390–540 °C and pressures of up to 646 bars (<2.6 km depth) from boiling hydrothermal fluids. A later condensation of vapor-rich inclusions resulted in a moderately saline fluid (8.4–11.2 wt % NaCl equiv) at temperatures between 311 and 392 °C, which were related to sericitic alteration, D-type veins, and associated metallic mineralization. Subsequent dilution of the moderately saline fluid at lower temperatures (205–259 °C) produced a less saline (1.4–2.9 wt % NaCl equiv.) fluid, which is likely associated with the late epithermal overprint.

“…It consists of gneisses, schists, and amphibolites intercalated with marble. Metagabbros-metadiabases and A-type granites of the Paleozoic to Triassic ages are also present [58,59,62]. The Cenozoic igneous evolution is characterized by four magmatic pulses spanning from the Late Paleocene to the Pliocene and includes I-type plutonic, sub-volcanic, and volcanic rocks, associated with calc-alkaline to high-Kcalcalkaline and shoshonitic affinities [56,62] (Figure 1).…”

Rare and Critical Metals in Pyrite, Chalcopyrite, Magnetite, and Titanite from the Vathi Porphyry Cu-Au±Mo Deposit, Northern Greece

et al. 2021

The Vathi porphyry Cu-Au±Mo deposit is located in the Kilkis ore district, northern Greece. Hydrothermally altered and mineralized samples of latite and quartz monzonite are enriched with numerous rare and critical metals. The present study focuses on the bulk geochemistry and the mineral chemistry of pyrite, chalcopyrite, magnetite, and titanite. Pyrite and chalcopyrite are the most abundant ore minerals at Vathi and are related to potassic, propylitic, and sericitic hydrothermal alterations (A- and D-veins), as well as to the late-stage epithermal overprint (E-veins). Magnetite and titanite are found mainly in M-type veins and as disseminations in the potassic-calcic alteration of quartz monzonite. Disseminated magnetite is also present in the potassic alteration in latite, which is overprinted by sericitic alteration. Scanning electron microscopy and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) analyses of pyrite and chalcopyrite reveal the presence of pyrrhotite, galena, and Bi-telluride inclusions in pyrite and enrichments of Ag, Co, Sb, Se, and Ti. Chalcopyrite hosts bornite, sphalerite, galena, and Bi-sulfosalt inclusions and is enriched with Ag, In, and Ti. Inclusions of wittichenite, tetradymite, and cuprobismutite reflect enrichments of Te and Bi in the mineralizing fluids. Native gold is related to A- and D-type veins and is found as nano-inclusions in pyrite. Titanite inclusions characterize magnetite, whereas titanite is a major host of Ce, Gd, La, Nd, Sm, Th, and W.

“…Two samples of felsic orthogneisses from this unit have been dated by the Pb-Pb zircon evaporation technique, giving ages of c. 570 and 587 Ma with whole-rock ϵNd values of −7.59 and −7.64, respectively. U-Pb isotopic dating of detrital zircon grains from the mylonitic quartzite of the Pyrgadikia unit shows a dominant age peak at c. 580 Ma (Himmerkus et al 2006;Abbo et al 2020). The Vertiskos unit occupies the central part of the SMM and is composed chiefly of felsic augen and mica gneisses that attained amphibolite-facies conditions (Dixon & Dimitriadis, 1984).…”

“…Liati et al 2016). U-Pb dating combined in some studies with Lu-Hf isotope tracer constraints have been conducted on igneous and detrital zircon grains from this terrane in order to chart in more detail crustal growth patterns of the SMM and Rhodope massif and enhance our understanding about the evolution of the European crust (Himmerkus et al 2007;Peytcheva et al 2015;Antić et al 2016;Abbo et al 2020). In order to investigate further the crustal evolution of the SMM, I present in this contribution new U-Pb and Lu-Hf isotope data from zircon grains of two (meta)-igneous units that crop out in a Greek segment of the SMM that remains underexplored: Ammouliani island in the Mount Athos gulf (Fig.…”

Zircon U–Pb and Lu–Hf isotope microanalysis was conducted in (meta)-igneous units of Ammouliani island to characterize crust-forming and reworking events in the Serbo-Macedonian massif. Zircon grains from an orthogneiss of the Vertiskos unit yielded a U–Pb crystallization age for the igneous precursor at 458.8 ± 11 Ma with dominantly subchondritic ϵHf values indicating reworking of Neoproterozoic basement. A weighted mean ϵHf value of 0.7 ± 2.4 from oscillatory zoned zircon grains of the Ouranoupoli granodiorite indicates juvenile crustal input at 52.1 ± 0.6 Ma. The U–Pb–Hf zircon archive records discrete stages in the crustal evolution of the Serbo-Macedonian massif.
