The ancient city of Atarneus is subject to geoarchaeological research focussing on
late Holocence man-environment interactions in the environs of ancient Pergamon
(western Turkey). Atarneus, situated on a volcanic butte on the edge of the Bakırçay
floodplain, was one of the most important poleis in this region in the second half of the
first millenium BCE. It’s influence declined when Pergamon extended its power around
the beginning of the common era. Intensive studies have been carried out to investigate
the rise and fall of Atarneus. However, these studies have concentrated on socio-cultural
aspects and little attention has been given to environmental changes. Geomorphological,
sedimentological (magnetic susceptibility, element analysis) and geochronological
(radiocarbon dating) investigations were conducted on alluvial fans at the break in slope
of Atarneus’ settlement hill.
Several alluvial fans connected to channels on the settlement hill were identified.
Generalized, the fans directly originating in the settled area consist from bottom to top of
well-rounded fluvial sediments, coarse colluvials and a reworked occupation layer. Radio
carbon dates show that before the rise of Atarneus floodplain conditions prevailed and the
