Zusammenfassung:Raw material provenance and procurement studies are an essential research line to infer landscape exploitation, mobility dynamics and territorial management among prehistoric hunter-gatherer groups. This paper proposes an original and intuitive method, the chert abundance ratio, aimed at quantifying lithic resource occurrence in the landscape while considering the geological natural factors of an area (chert-bearing formation extent, thickness, occurrence index, size and chert content). The resource availability can be statistically compared to any archaeological assemblage distribution to define the procurement strategies, whether generalist or selective, and the mobility patterns. The study area, the north-east of the Iberian Peninsula, focused in the Prades Mountains, represents a regional scenario with high chert disposal shared by several Late Upper Palaeolithic occupations. The discrimination of the procurement areas is used as a parameter for outlining the foraging radius and the territorial range, contributing to an understanding of several aspects of the settlement, such as site functions, occupation length or intensity and group size.
