The aim of this paper is to discuss conceptual and methodological issues related with the archaeological study of lithic landscapes and exemplify the approach with a case study (artifact distribution data from east-central Argentina). A lithic landscape-understood as the co-occurrence, in a given geographic space, of different structural units each one composed by a raw material source and the complete set of unmodified and human-modified pieces of rock extracted from that source and then transported, used, and discarded across the landscape (i.e., a scatter area)-can be modeled using kriging, a geostatistical interpolation tool useful for integrating scattered information into coherent spatial models. The case study allows for the examination and discussion of, on one hand, the relationships between the type and location of the
