Evidence of Holocene ashes from Central Anatolia in the deep-sea sediments of the Eastern Mediterranean

A new paper published by Hamann et al. about the first evidence of Holocene ash layers from the central Anatolia in the deep-sea sediment from the Eastern Mediterranean. The paper will appear in the Journal of Quaternary Research, with co-authers from Hacettepe University, Dr. Orkun Ersoy and Dr. Erkan Aydar. Radiometric, stratigraphic and sedimentological data shows that the tephra was deposited between 8970 and 8690 cal yr BP. They compared the tephra with proximal to medial-distal tephra deposits from well-known Mediterranean ash layers and ash fall deposits from the Central Anatolian volcanic field using electron probe microanalyses on volcanic glass shards and morphological analyses on ash particles. They found a correlation with the Early Holocene ‘Dikkartın’ dome eruption of the Erciyes Volcano, more than 600 km to the north. doi:10.1016/j.yqres.2009.12.004
