Hasandaǧı, Acıgöl and Göllüdaǧı) known as the late Quaternary and their widespread volcanoclastic products.Recent studies have suggested at least 11 events at around Acıgöl Caldera for the last 180 ka and 2 events at Hasandaǧı Stratovolcano for the last 30 ka.The growth of U, can be used over a time range from a few hundred to half a million years.Calcite precipitated from running or dripping water in springs and caves, as well as marls and soil-deposited calcretes may be spatio-temporally associated with archaeological materials; they can be dated by U measurements with a precision of ±5–10% of the age (by alpha counting) or ±1% (by mass spectrometry).
Because all dating techniques may be subject to considerable error, reliability should be assessed by stratigraphic consistency between results of different dating methods or of the same method.
AA(Department of Geological Engineering, Eskisehir Osmangazi University, TR 26480, Turkey), AB(Department of Geological Engineering, Hacettepe University, TR 06800, Turkey), AC(School of Geography, Planning & Environmental Management, The University of Queensland, QLD 4072, Australia) Dating of late Quaternary volcanism is crucial to understanding of the recent mechanism of crustal deformation and future volcanic explosivity risk of the region.
However, radiometric dating of volcanic products has been a major challenge because of high methodological error rate.
Relative-dating techniques are nearly always applicable but are not precise and require calibration.
Correlation techniques are locally useful and depend on recognition of an event whose age is known, such as a volcanic eruption or a paleomagnetic reversal.
