The Minoan Thera eruption of the Bronze Age is the most significant Aegean explosive volcanism. The eruption resulted in caldera collapse. We studied the Minoan volcano-tectonic event from the viewpoint of sedimentology and hydraulics. On the Aegean Sea coast of Turkey and Crete we found traces of tsunamis. The tsunami layers are overlain by felsic tephra. The mineralogical characteristics of volcanic tephra and AMS radiocarbon dating on foraminiferal tests show that the tsunami layers are correlative to the Minoan event. The results of our numerical simulation on the tsunami show that a destructive train of waves caused by the caldera collapse reached the Aegean Sea shore within 2.5 hours and the great surf set up by arrival of waves washed the coast. We conclude that the Minoan tsunami hazards damaged the maritime economy in the coastal areas of Aegean islands and Turkey.


Tertiary volcanism of the Galatia province, north-west central Anatolia, Turkey
Wilson, M; Tankut, A; Güleç, Nilgün Türkan (1997-12-01)
Large volumes of trachyandesitic-dacitic lava flows and pyroclastics of Miocene age are associated with small volumes of alkali basalt lava flows in the Galatia volcanic province, northwest Central Anatolia, Turkey. The volcanism postdates continental collision, occurring in a transtensional tectonic setting associated with movement along the North Anatolian Fault zone. Major and trace element (including REE) and Sr-Nd isotope data and K-Ar ages for representative samples of mafic-intermediate volcanic rock...

Thin beds of tephra (K-bentonites) formed by the diagenesis of volcanic ash are exposed within the limestone-dolomitic limestone successions of the Yilanli formation at Zonguldak and Bartin in northwestern Turkey. They were deposited on the Middle Devonian-Lower Carboniferous shallow carbonate platform of the Zonguldak terrane. In this study, K-bentonite samples collected from Gavurpinari and Yilanli Burnu limestone quarries are investigated in order to reveal their mineralogical and geochemical characteris...
Hydrogeochemical Properties of Geothermal Fields at Northeastern Anatolia
Aydın, Harun; Karakuş, Hüseyin; Mutlu, Halim; Güleç, Nilgün Türkan; Hılton, Davıd (null; 2016-05-16)
In Anatolia which is one of exceptional continental regions hosting both Neogene volcanism and tectonism, the geothermal potential is quite high due to unique geological and tectonic structures. In recent years, the geothermal resources in western Anatolia, whose geothermal potential is well defined, are successfully used in a wide range of applications such as energy production, district heating, thermal tourism and greenhouse heating. However, the geothermal resources of northeastern Anatolia (NEA) have b...
Assesing the Usage of Calcium and Magnesium Hydroxide Nanoparticles as Consolidant for Dolostones.
Karahan Dağ, Fulya; Tavukçuoğlu, Ayşe (2018-12-01)
Dolostone has been abundantly used in the construction of monuments during archaeological periods in Anatolia. Several of those monuments have some decay problems to be assessed and need conservation treatments to be developed. In the study, it was aimed to prepare a nanodispersive solution from the dolostone itself and follow its carbonation mineral phases in order to obtain a compatible consolidation treatment for dolostone. A mixture of calcium and magnesium hydroxide nanodispersive solution in ethyl alc...
Volcano stratigraphy and petrogenesis of the Nemrut stratovolcano (East Anatolian High Plateau): The most recent post-collisional volcanism in Turkey
Ozdemir, Y; Karaoglu, O; Tolluoglu, AO; Güleç, Nilgün Türkan (Elsevier BV, 2006-02-28)
The Nemrut stratovolcano, with its well defined summit caldera, is the most recent volcanic eruption center (1441 A.D.) in the East Anatolian High Plateau, one of the best examples of an active colllision zone. Widespread volcanism has been active in this region for the last similar to 10 Ma, producing large volumes of lavas and pyroelastics covering a broad belt, across the Bitlis Suture Zone, from the Anatolian plate in the north to the Arabian plate in the south.
