Abstract (in english)
   At the southeastern margin of the Bohemian Massif in Lower Austria during the whole Pleistocene a complex development of loess can be noticed. Multiple phases of erosion and accumulation interchange with brakes in sedimentation and erosion, causing many fossil soils in this area. The aim of this publication is to characterize and to classify fossil soils, recorded during geological mapping, into a stratigraphical scheme by paleopedological investigation and soils inside the loess series. These older soils from Lower to Middle Pleistocene (pedocomplex PC V-XII) are best preserved directly on the southeastern margin of the Bohemia Massif. Younger fossil soils of PC III sporadically occur but soils of PC II and PC I nearly are missing. East of the river Schmida fossil soils of PC VII-XII are preserved in the loess series that are of lower extent and accumulation. Additionally there is lack of fossils soils of younger soil complexes too.
   There is evidence for a phase of intensive erosion after sedimentation of Upper Pleistocene loess series and soils of PC I-II, that removed all younger loesses and fossil soils but also other quaternary sediments like flucial terraces. All investigated soils are highly polygenetic. Intensity and number of polygenetic sections depend on the development of the quaternary climate and on sedimentary but also pedogenetic cycles. Most of the soils are autochthonous to parautochthonous or correspond to fossil soil-sediments; only few of them are relic soils. They mostly originate on loess but only few on clay or acidic sandy gravels of the Tertiary. Soils of the braunlehm-type finally developed during the youngest warm peroid of the Mindel (Middle Pleistocene). They occur as relics of the basal parts of PC VII-XII either in typical development or strongly brown erathified.
   In the Cromer interglacial (Günz/Mindel, PC X) and in older warm periods of the first order the brown plastosols often are replaced by rubefied and strongly illimerized braunlehms and rotlehms. Soils of the ferreto-type developed on acidic sands and gravels under the same conditions. A complete development of soils, preserved from the Holstein interglacial (Mindel/Riss, PC VI and V) is represented by pairs of brown earthified braunlehm-like parabraunerdens, most strongly developed on the base of the soil of PC VI. An illimerized soil, studied in addition to the older soils corresponds to the climatic optimum of the last interglacial (Eem, Riss/Würm) evidenced by the lower soil of PC III (Stillfried A)
