Description :
The AA. investigate the paleo-channel fill at Stöttham using a combination of various field sedimentological and pedological methods together with extensive laboratory investigations, all with the aim of characterizing the genesis of the relevant paleosoils and sediments. They also use both relative and absolute dating techniques, including sediment and archaeological stratigraphy, radiocarbon dating of charred organic matter and optical stimulated luminescence dating using quartz to provide a chronostratigraphy for the paleo-channel fill. Taken together, the sedimentological, pedological and chronological data argue strongly against any catastrophic geomorphological event as the origin of the channel fill at Stöttham. On the contrary, the studies provide consistent evidence for colluvial processes being the main mechanism for filling the channel during the Holocene; such processes are often linked to settlement phases in this area.
