Abstract Lithic materials are among the most abundant items in the archaeological record of the Central Ranges and their adjacent plains. The studies carried out with lithic artefacts use different spatial scales, as well as field and laboratory methodologies. However, the research programs oriented to the detection of lithic sources and archaeological quarries do not have in this region a similar development in comparison to other regions of Argentina. This paper presents the initial lines of a macroregional scale project, specifically oriented to their study. The results achieved so far allowed the identification of numerous quarries and lithic sources in San Luis, Córdoba, La Rioja, and Catamarca provinces. We propose a model of deposit of the siliceous rocks which allows to understand the genesis of the identified rocks. On the other hand, it is the first wide-scale predictive occurrence model for the center of Argentina.

Keywords : Siliceous rocks; Pampean mountain ranges and plains; occurrence model; predictability model.
