The section is located\r\nin the Central Balkan, at the transition zone between Atlantic, continental and Mediterranean climate regimes and\r\nis therefore potentially extraordinary sensitive to past and present climatic changes. Especially in the context of\r\nearly human migration, this region is not intensively studied and has potential to contribute valuable information.\r\nThis is the reason why it is investigated in the frame of the CRC 806 \u201cOur Way to Europe\u201d project. This project\r\nfocuses on the climatic changes and their influence on the dispersal of anatomically modern human (AMH). For\r\nthe loess-paleosol sequence exposed in a quarry in Stala\u00b4c, a multi-proxy approach combining geochemical and\r\nsedimentological analysis and luminescence dating is applied. This contribution focusses on the luminescence\r\ninvestigations.\r\nThe luminescence characteristics of six samples were analyzed using the optically stimulated luminescence\r\nsignal of quartz by means of the single-aliquot-regenerative-dose (SAR) protocol and the infrared stimulated\r\nsignal of feldspar (within polymineral samples) by means of the post-infrared-infrared (pIRIR) protocol. While the\r\nfine quartz grain (4-11\u0016m) samples show a preheat dependency of equivalent doses that makes them unsuitable for\r\ndating, the polymineral fine grain samples measured by pIR50IR290 behave satisfactorily: plateaus within a first\r\nIR stimulation temperature test, good dose recovery ratios, low residual doses, high precision and low uncertainty\r\nsupport the established age chronology ranging from 35.2 \u0006 1.8 ka to 168 \u0006 9 ka. A tephra within the MIS 6/L2\r\nloess layer was bracket dated, and combining these ages suggests an age between ca. 140 and 175 ka (2\u001b).\r\nBased on the presented results we introduce a new geochronology of the Stala\u00b4c section, indicating that the\r\npreviously suggested correlative stratigraphy (Kosti\u00b4c and Proti\u00b4c, 2000) requires significant revision. By using\r\nluminescence dating we demonstrate that the sediments found are older than previously proposed. This reveals\r\nthat environmental conditions during the last two interglacials (MIS 7 and MIS 5) were different, but it also shows\r\nthat MIS 5 and MIS 3 had relatively similar conditions.\r\nReference\r\nKosti\u00b4c, N., and Proti\u00b4c, N.
