A 23 m thick succession of Quaternary deposits was investigated at Sarengrad, Eastern Croatia. A geochronological study was performed on loess samples using luminescence dating. An elevated temperature post-IR infrared stimulated luminescence (post-IR IRSL) dating protocol was applied. Performance tests showed that the protocol is suitable for the samples under study. The post-IR IRSL based chronology implies that, contradictory to previous correlations, not the Last Glacial - Last Interglacial cycle but a Middle Pleistocene loess-palaeosol sequence is exposed at Sarengrad II. Based on our ages, the lowermost loess is correlated to oxygen isotope stage (OIS) 9-10 and the double palaeosol at the top of the section most likely correlates with OIS 7. The Last Glacial record is exposed at the nearby Sarengrad I section. Furthermore, a heavy and light mineral analysis was performed on the investigated section as well as on the previously investigated Sarengrad I section, showing that the mineral association is typical for Quaternary deposits of the Pannonian basin.

Aeolian dunes controlled by regional climate have been formed in many coastal areas of the Mediterranean Sea during the Quaternary. Generally, they are formed under a landward-blowing wind, and comprise numerous reworked penecontemporaneous shallow-marine carbonate grains. Along the eastern mid-Adriatic Sea, late Pleistocene aeolian and alluvial sands occur as isolated patches in karstic depressions on several islands and the Pelješac Peninsula. At most localities, the sands consist of a mixture of mostly carbonate rock fragments and siliciclastic material. A higher proportion of shallow-marine bioclasts was found only at one locality. The terrestrial material was transported to the coastal area by at least two rivers: paleo-Cetina and paleo-Neretva River, and was subsequently reworked and transported by wind, resulting in aeolian deposition. Sandy units of various thicknesses exhibiting sharp erosional bedding planes and cross-bedding are interpreted as representing aeolian dunes and sand sheets controlled by a complex wind regime. The mineralogical composition at almost all localities indicates near-river flood plains as the main sand source. Although the area was affected by strong winds blowing landward and parallel to the coast, they significantly deviated due to the local topography produced by the tectonically deformed and karstified carbonate basement. In this way, the late Pleistocene aeolian deposits on the mid-Adriatic islands differ from deposits from most Quaternary Mediterranean coastal aeolian belts, as they contain very small quantities of penecontemporaneous shallow-marine carbonate grains and were deposited by winds blowing in varying directions instead of prevailing landward-blowing winds.
