SAR OSL DATING OF 63-90 μm QUARTZ EXTRACTED FROM AN EEMIAN (PRESUMABLY LACUSTRINE) SEDIMENTARY SECTION AT FLOREŞTI ON THE SOMEŞUL MIC VALLEY

Full text

A double-SAR OSL protocol was applied on 63-90 μm quartz extracted from an exposed sedimentary succession from Floreşti on the Someşul Mic Valley, central-northern Romania in order to determine its depositional age. The equivalent doses measured for the three samples analyzed were 291 ± 17 Gy, 331 ± 27 Gy respectively 348 ± 17 Gy. The optical ages obtained were found in agreement within error limits 139 ± 15 ka, 133 ± 16 ka and 134 ± 13 ka, respectively. These new chronological data support the assumption that the analyzed sedimentary record was deposited during the Eemian Interglacial in periglacial settings (probably lacustrine deposits with high sedimentary input).
