Present world landscapes reflect past geomorphological processes and landforms. In particular, Quaternary landscape evolution plays a key role in the explanation of the present day topography and it influences the function of modern geosystems. Furthermore, Quaternary landscape formation and its impact on active geomorphic systems are increasingly targets of integrated interdisciplinary studies as it forms an important basis for many socially relevant issues.

The evolution of paleosurfaces is controlled by a complex network of external and internal influences. They represent a zone of exchange between soil/parent rock, the ecosystem, and the atmosphere. Terrestrial archives give evidence of topographical and ecological changes at different time scales, reflecting paleoenvironmental fluctuations at a local, regional and global scale. Considering that recently a number of efficient dating methods are available, continental soil-sedimentary sequences can provide valuable data for the reconstruction of paleotopography and paleoenvironment.

Within this session we intend to present actual studies on landscape evolution and chronostratigraphy during the Quaternary, mainly during the Brunhes Chron. Presentations should be focused on Quaternary sediments, geomorphological processes and forms on spatial and temporal scales and the relevance for modern landscapes and geosystems.
