“…The only known source with mainly alkaline volcanism in the surrounding of Lake Prespa are the volcanic districts of the Italian Peninsula, which also would match with predominant westerly winds in the region. Volcanic products of the Aegean area (e.g., Greece, Santorini) and Central Anatolia (e.g., Turkey) show mainly calc-alkaline affinity (e.g., Keller et al, 1990;Druitt et al, 1995;Paterne et al, 2008) and those of Germany (Eifel volcanic district) and France (Massif Central) have never been recorded close to the study area (e.g., Van den Bogaard, 1995;Schmincke et al, 1999;Walter-Simonnet et al, 2008;Riede et al, 2011). Traces of the Vedde Ash from Iceland were recently found in the Lake Bled, Slovenia (Lane et al, 2011a), but not yet on the Balkan Peninsula.…”

A detailed tephrostratigraphic record, which dates back to Marine Isotope Stage (MIS) 5b (ca. 91 kyr), has been established from a 17.76 m long core (Co1215) from Lake Prespa (Macedonia, Albania and Greece). A total of eleven tephra and cryptotephra layers (PT0915-1 to PT0915-11) were identified, using XRF scanning, magnetic susceptibility measurements, and macro- and microscopic inspection of the sediments. The major element composition of glass shards and/or micro-pumice fragments indicates that the tephras and cryptotephras originate from the explosive volcanism of Italy. Eight tephra and cryptotephra layers were correlated with specific volcanic eruptions: the AD 512 eruption of Somma-Vesuvius (1438 cal yr BP), the Mercato eruption of Somma-Vesuvius (8890 ± 90 cal yr BP), the Tufi Biancastri/LN1-LN2 eruption of the Campi Flegrei (14 749 ± 523 cal yr BP and 15 551 ± 621 cal yr BP), the SMP1-e/Y-3 eruption of the Campi Flegrei (30 000-31 000 cal yr BP), the Campanian Ignimbrite/Y-5 eruption of the Campi Flegrei (39 280 ± 110 cal yr BP), the SMP1-a event of Ischia Island (around 44 000 cal yr BP) and the Green Tuff/Y-6 eruption of Pantelleria Island (around 45 000 cal yr BP). One tephra could be attributed to the volcanic activity of Mount Etna, but probably represents an unknown eruption at ca. 60 000 cal yr BP. Cryptotephras PT0915-6 and PT0915-10 remain unclassified so far, but according to the presented age-depth model these would have been deposited around 35 000 and 48 500 cal yr BP, respectively. Some of the tephras and cryptotephras are recognised for the first time in the Balkan region. The tephrostratigraphic work provides important information about ash dispersal and explosion patterns of source volcanoes and can be used to correlate and date geographically distant paleoenvironmental and archaeological archives in the central Mediterranean region. Moreover, the tephrostratigraphic work in combination with radiocarbon and electron spin resonance (ESR) dating is a precondition for paleoclimatic reconstructions inferred from the sediment succession Co1215

“…250 m. Andesitic lava flow sequences, some of which flowed up to 1.5 km radially, drape the flanks of the dome structure (e.g. Acıgöl complex in Turkey, Druitt et al, 1995; Nemrut Caldera in Turkey, Karaoğlu et al, 2005). Intense potassic and argillic-type hydrothermal alterations are observed at the southern part of the edifice, while the centre of the volcano has been subjected to magma-water interactions such as pyroclastic surge deposits for explosive and baked surfaces along lavas and unconsolidated lacustrine deposits for effusive volcanism (e.g.…”

“…The volcanics vary from rhyolite to basalt (Beekman, 1963;Pasquare, 1968;Keller, 1974;Innocenti et al, 1975;Batum, 1978a;Ercan, 1987;Ercan et al, 1987Ercan et al, , 1990Druitt et al, 1995;Aydar and Gourgaud, 1998). Most of the volcanics have a medium to high-K calc-alkaline composition that is typical of the collisionrelated volcanism.…”
