The extensive Mesolithic site of Kerkhove-Stuw was located on the top of a natural levee,adjacent to a palaeochannel of the river Scheldt. Subsequently (from the boreal onwards),the landscape was covered by approximately 4,5m to 9m of peat and alluvial clay. The infillof the palaeochannel deposits were studied by means of a high-resolution multi-proxy analysis(i.e. pollen, microcharcoal, loss on ignition, magnetic susceptibility, granulometry, molluscfauna .etc.) to reconstruct the varying ecological settings of the prehistoric occupation.The excavations yielded thirteen spatially distinct concentrations of lithic artefacts thatcould be dated to the Early, the Middle and the Late Mesolithic, based on typology. Thiswas partly confirmed by 14C-dates on single entity charred hazelnut shells. Additionally,the site had great potential for a comprehensive technological analysis thanks to the overalllow-density of the lithic concentrations and the diversity of macroscopically discernable rawmaterial categories.Besides lithics, a considerable amount of unburnt and burnt bone fragments, and palaeob-otanical remains were documented. The preservation of a faunal assemblage (dominated byroe deer and wild boar, but also comprised of fur animals and fish remains) is exceptionalfor the Early and Middle Mesolithic in the region and will allow us, for the first time, to gaina better understanding of Mesolithic subsistence practices.Finally, to determine the inter- and intrasite functional properties and aspects of the tech-nological organization of the thirteen lithic concentrations, the spatial distribution of thedifferent types of material remains are studied, combined with a technological and microwearanalysis of the lithic artefacts. For example, the location of ten possible surface hearths couldbe derived from heavily burnt lithic artefacts and burnt organic remains. So far, preliminary results from the technological analysis indicate the presence of several expedient technolo-gies, more elaborate opposed striking platform ...
