摘要：

A double-SAR OSL protocol was applied on 63-90 mu m quartz extracted from an exposed sedimentary succession from Floresti on the Somesul 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).
