The Middle and Late Pleistocene loess-paleoseol sequences of the Titel loess plateau, northern Serbia, have been investigated in detail in the last several years. It was discovered that those sequences hold the key for understanding climate and environmental changes for the 650 ka. Magnetic susceptibility data which was measured together with other paleoclimate proxies in complex studies is used for correlating Vojvodinian loess-paleosol sequences with other similar ones across Eurasian continent and SPECMAP paleoclimatic model.
Magnetic susceptibility and grain size data has proven to be a good tool for developing Pleistocene time scale (e.g. Heslop et al., 2000, Ding et al., 2002; Sun et al, 2006, Sun and Huang, 2006).
Similar approach was used for loess-paleosol sequences of the Titel loess plateau. Preliminary results were obtained by tuning magnetic susceptibility grain size records of the synthetic Titel loess-paleosol sequence with insolation values given by Berger, 1990.
Depth scale of investigated sequence was converted to time scale using mathematical functions and thus enabled the correlation to insolation values.
Results show that the periods of increased insolation values correspond well with the periods of intensive soil formation, interglacial periods.
In the future, it is planned to developed orbitaly tuned time scale for loess deposits in Serbia using magnetic susceptibility record and grain size data. Also, record of paleoclimatic and orbital cycles inscribed in loess-paleosol sequences have to be tested.
