Abstract :
[en] Since the introduction of direct push sensing, and more specifically, cone penetration testing, in prehistoric paleolandscape mapping, applications have been limited to mapping relatively thick and lithologically contrasting sedimentary units in fluvial and estuarine floodplains. However, this study investigates techniques to map thinner and less contrasting sediments, and soil horizons in soft soils outside these floodplains as well. Therefore, cone penetration testing and electrical conductivity logging are assessed in combination with the first paleolandscape mapping application of direct push, in situ video imaging in test cases situated in the polders, coversands, and loess belt of Belgium. The results reveal that the discrimination potential of archaeologically relevant, litho- and pedostratigraphic units through direct push sensing is increased in the respective regions. Despite the necessity of hardware updates and further developments in video data processing, a combination of cone penetration testing, electrical conductivity logging, and in situ video imaging is readily applicable to extensive mapping of deeply buried prehistoric paleolandscapes. © 2020 Elsevier B.V.
