A detailed environmental magnetic analysis was carried out on a 10 m vertical profile exposed in a brickyard at Madaras in order to reconstruct the course of palaeoclimate during the late Upper Pleistocene. Madaras is located in the very South of Hungary at the northern rim of the Bácska loess plateau. In this area, thick loess resting on aeolian sands was accumulated during the Middle and Late Pleniglacial (Hupuczi & Sümegi 2010).

The malacofauna from this profile revealed specific changes during the late Upper Pleistocene. This suggests a number of dynamic climate and local environmental fluctuations in the Bácska loess area during the Middle and Upper Pleniglacial. Most interesting is the contrasting difference of the malacological record in this area to the other loess regions of Hungary (Hupuczi & Sümegi 2010). Here we present the first results of a thorough rock magnetic investigation of this loess-paleosol profile which will hopefully lead to a better understanding of the paleoclimate and paleoenvironmental conditions and variations in the South Pannonian Basin.

The rock magnetic results obtained so far reflect sensitively the intensity of pedogenesis on the study site and provide additional and independent proxy parameters, which will complement the palaeontological and sedimentological results. A correlation to the course of palaeoclimate recorded in the Greenland ice cores will be discussed.
