The last two decades, intensive archaeological research in the Campine region shed new light on its Final Palaeolithic and Early Mesolithic habitations (De Bie & Van Gils 2009). However the focus of this research was mainly on settlement systems and land use. Thorough investigations of the material culture in this area have remained rather limited (Van Noten 1978; De Bie 1999). Within this project we attempt to define and explain the technological changes across the Pleistocene-Holocene transition for this region. Similar studies of lithic technology have been executed for the Meuse (De Bie & Caspar 2000) and Scheldt basin (Perdaen 2004) and for the French Loess regions (Valentin 1995, 2006; Ducrocq 2001).
The most important question is what these technologies, and the (possible) differences between them, can learn us on choices and behaviour of the involved societies. To comprehend the variations through time, we need to understand how lithic technology was approached in both the Final Palaeolithic and the Early Mesolithic. This cannot be achieved by a mere consideration of formal tool types, which hardly permits an interpretation of observed differences, but requires a reconstruction of the complete chaîne opératoire. The technological choices are not only registered; instead there is a systematic search for possible explanations for this human behaviour.
