| Sumario: | The main goal of this study is to understand the practices and management of technological production of the hunter-gatherer groups that inhabited the Tapalqué creek basin (Olavarría, Buenos Aires). The results of the techno-morphological analysis of the lithic assemblage from the Laguna Blanca Chica site are presented and discussed. Also, the function of a chert accumulation in a shallow lake (possibly a cache or knapping locus) is assessed. The different stages of the operational chains were reconstructed to identify technological practices and recognize the knapping techniques (debitage, façonnage, and retouch) involved in the production processes of the lithic artifacts. The raw material more frequently used is chert, followed by orthoquartzite with a wide range of colors. In smaller proportions, silica, quartz, silicified dolomite, limestone, and granitoid rocks are also present. Results reveal certain differences in the treatment of the main tool stones, which are reflected in varying technological activities and in the modes of tool manufacture. Finally, the technological practices identified at Laguna Blanca Chica are compared with those from other archaeological contexts within the central Pampa grasslands |
