Testing polymineral post-IR IRSL and quartz SAR-OSL protocols on Middle to Late Pleistocene loess at Batajnica, Serbia.

ABSTRACT: The loess-palaeosol sequence of Batajnica (Vojvodina region, Serbia) is considered as one of the most complete and thickest terrestrial palaeoclimate archives for the Middle and Late Pleistocene. In order to achieve a numerical chronology for this profile, four sets of ages were obtained on 18 individual samples. Equivalent doses were determined using the SAR protocol on fine (4-11 μm) and coarse (63-90 μm) quartz fractions, as well as on polymineral fine grains by using two elevated temperature infrared stimulation methods, pIRIR ₂₉₀ and pIRIR ₂₂₅. We show that the upper age limit of coarse quartz OSL and polymineral pIRIR ₂₉₀ and pIRIR ₂₂₅ techniques is restricted to the Last Glacial/Interglacial cycle due to the field saturation of the natural
