Abstract The following article presents the technomorphological analysis of the Médano Santa Clara site lithic assemblage, visited for the first time by Guillermo Madrazo in 1970. The importance of re-studying this assemblage lies in the fact that is a site located in the southwestern sector of the Central Pampean Dunefields, at variable distances from the main raw material outcrops. Based on the contextual information and the characteristics of the record, it is suggested that the site was occupied in the late Holocene and during the Hispanic-Indigenous contact. The new data indicates a greater exploitation of chert and orthoquartzites from the Tandilia hills, followed by rocks from the xerophytic woodland of the Dry Pampas (silicified limestone and chalcedony) and Ventania hills (metaquartzite and rhyolite). Differences were observed in the procurement strategies and the methods and techniques employed between those majority and minority rocks. The results suggest the optimal use of the rocks, which should be transported from long distances. By last, the representation of the raw materials in the site contrast with other contexts from the study area, pointing out to a differential use of the rocks towards the western sector.

Keywords : Techno-morphological analysis; Procurement strategies; Late Holocene; Pampa grasslands.
