This paper presents information regarding the prehistoric exploitation of a red chert variety based on the exploitation of one lithic primary procurement source called Punta Norte, located on the Atlantic coast of Santa Cruz province, Argentina. The use strategies of this rock at a local scale are evaluated based on the study of characteristics of lithic artefactual assemblages recorded in archaeological contexts located at varying distances from the source. Knowing the origin of the chert -represented so far by only one source- allowed the spatial trajectory of the rock to be reconstructed on a small scale. The observed trends suggest that the human groups that occupied the coast during the middle and late Holocene carried out an intensive exploitation of red chert at the micro-local level, in various contexts, and mainly in the vicinity of the its source.

Palabras clave : Red chert; Primary source; Exploitation; Hunter-gatherers; Patagonia.
