MESSINEO, Pablo G.  y  D'AUGEROT, Lázaro. Análisis preliminares de los materiales líticos provenientes de la Laguna Blanca Chica (Olavarría, Buenos Aires). Intersecciones antropol. [online]. 2004, n.5, pp.187-190. ISSN 1850-373X.

In this paper we report some preliminary results of the study of lithic material recovered from Laguna Blanca Chica, Olavarría district, Buenos Aires Province. The main aim of the study is to gain knowledge of aspects related to the acquisition of, and technological process involved in, raw material exploitation. The results obtained show that more than 50% of the principal lithic resource used consisted of chert. Formal and informal artefacts were also made using mainly chert as the raw material. The high frequency of this raw material in the lagoon is similar to other sites in the area (e.g., Laguna La Barrancosa 2, Arroyo Tapalqué 1), and may be due to its high natural availability and good chipping quality. Even so, a great variability of quartzite rocks was observed, showing that different geological formations were exploited.

Palabras clave : Raw material exploitation; Chert; Formal and informal tools; Tapalqué stream; Pampean region.
