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 Este trabajo tiene como principal objetivo conocer las prácticas y gestiones de producción tecnológicas llevadas a cabo por los grupos cazadores-recolectores que habitaron la cuenca del arroyo Tapalqué (partido de Olavarría, Buenos Aires). Con este propósito, se presentan y discuten los resultados obtenidos del análisis tecno-morfológico del conjunto lítico procedente del sitio Laguna Blanca Chica. Para identificar las prácticas tecnológicas y reconocer los modos de talla (debitage, façonnage y retoque) involucrados en las trayectorias de producción de los artefactos líticos se reconstruyeron las diferentes etapas de las cadenas operativas. En líneas generales, la materia prima que se encuentra mayormente representada es la ftanita, seguida por la ortocuarcita con una amplia diversidad de colores y, en proporciones menores, por sílice, cuarzo, dolomía silicificada, caliza y rocas granitoides. Los resultados obtenidos permiten identificar ciertas diferencias en el tratamiento de las principales rocas talladas, lo cual se ve reflejado en las diversas actividades tecnológicas y en los modos de manufactura de los artefactos formatizados. Por último, se discute la funcionalidad de una acumulación de ftanita en la laguna (escondrijo o locus de talla) y se comparan las prácticas tecnológicas identificadas en el sitio Laguna Blanca Chica con otros contextos arqueológicos del centro de los pastizales pampeanos.
