This work is a first attempt to map the flint distribution from the specialised mining sites for Northern France and Belgium by meaning of the examples of Jablines (Seine-et-Marne, France) and Spiennes (Hainaut, Belgium). The aim is to measure their impact on the settlements’ lithic economy and to evaluate their respective influence. The study shows a long distance distribution over more than 200 km. It allows us also to sketch preferential distribution routes for the different raw materials which are connected in some cases with cultural areas and overlap them in other cases.
