Abstract

A layer of volcanic ash (4 cm maximum recorded thickness) is present at ∼250 cm depth in littoral sediments of Gölhisar Gölü; a small intramontane lake in Southwest Turkey. The major-element glass chemistry, determined by electron microprobe, is characterised by a rhyolitic composition. Trace-element data, determined by solution inductively coupled plasma mass spectrometry (icp-ms) match previously reported results for proximal pumice samples from Santorini and Crete. Peat immediately below the tephra deposit has yielded radiocarbon ages of 3330±70 yr bp and 3225±45 yr bp (calibrated age range 1749–1406 bc).
