The loess-palaeosol sequence of Datthausen, SW Germany: Characteristics, chronology, and implications for the use of the Lohne Soil as a marker soil

摘要: Abstract A new loess-palaeosol sequence from the westernmost loess area along upper Danube River in SW Germany is presented. The profile Datthausen comprises a of Middle Pleniglacial (MPG) and Upper (UPG) palaeosols, separated by prominent erosional discontinuity. uppermost MPG palaeosol consists two olive-brown horizons, showing morphological characteristics “Lohne Soil” that represents many profiles humid regions central Europe. Sedimentological, palaeopedological micromorphological analyses, combined with luminescence dating, were carried out. Compared to Nussloch Schwalbenberg II Rhine region, shows more intense pedogenesis, mainly due its position depression lower loess-accumulation rates. Further, MPG/UPG transition at seems date later time, likely matching Greenland interstadial (GIS) 4 and/or GIS 3, rather than 7 5. We conclude Lohne Soil reliable pedostratigraphic marker, whereas use as chronometric marker sensu stricto (which should have formed during one well-defined phase soil formation) impeded it evolved several interstadials. Its lato may over phases impeded, too, chronological different not be specific enough. differences pedogenesis chronology between on side other are attributed site-specific factors such topography. influence these local scale prevail general climatic regime controlling formation regional level. Therefore, spatial diversity palaeosols needs considered when marine ice-core records for evaluating impact climate forcing terrestrial palaeoenvironments.
