ALBERTI, Jimena. Exploring labor investment trends in lithic assemblages from the northern coast of San Matías gulf, Río Negro province (Argentina). Zaranda ideas [online]. 2012, vol.8, n.2, pp.83-100. ISSN 1853-1296.

In this paper we study the lithic artifacts of the Northern coast of San Matías Gulf (Río Negro province) from a morphologic-descriptive macroscopic approach. In this sense, we use the notions of "work investment" and "technique class" for the first time in order to distinguish efforts of manufacture in the making of the different artifact classes that compose the assemblage. This perspective is integrated with the notion of risk to relate the efforts in the manufacture and the environmental and resource exploitation conditions in which the hunter-gatherers that inhabited the area may have lived. Also, we consider the different lithic raw materials that were used to make the artifacts. We conclude that, in general, the assemblage exhibits a low level of energy investment in its manufacture, which could be related to a low and/or none conservation of lithic raw materials in a context risk's low level in the resource exploitation.
