          Abstract

          Los materiales recuperados de excavaciones arqueológicas han sido afectados por diversos procesos post-depositacionales; ya sea de carácter natural como así también antrópico. Estos procesos ocasionan traslados y reorganización de los objetos alterando, en gran medida, la integridad de los mismos. En tal sentido, la evaluación de los múltiples procesos culturales y naturales que intervienen en la formación de los depósitos arqueológicos, es una herramienta fundamental para inferir las condiciones que contribuyeron a la formación de los sitios arqueológicos en general. Los objetos líticos tallados son indicio material, a partir del cual, se pueden realizar estudios de procesos de formación y comportamiento del registro arqueológico mediante análogos experimentales. En este caso, el objetivo del trabajo ha sido profundizar los conocimientos acerca de estos procesos y de su accionar sobre los rastros de uso detectados en los artefactos líticos del sitio arqueológico Cueva Maripe (Santa Cruz, Argentina), con ocupaciones humanas desde inicios del Holoceno. La acción del agua como agente corrosivo pudo haber influenciado las modificaciones de las superficies y filos del material lítico, afectando diferencialmente el grado de preservación de los microrrastros en los distintos sectores de la cueva. Para evaluar la variabilidad funcional de artefactos, presentamos los resultados obtenidos de la aplicación de dos vías analíticas independientes: análisis funcional y análisis diatomológico.

          Translated abstract

          The materials recovered from archaeological excavations, has been affected by different post depositional processes, whether natural or anthropic. This processes results in transfer, mix and reorganization of the objects limiting to a large extent, the integrity thereof. In this sense, the assessment of multiple cultural and natural processes involved in the formation of archaeological deposits, is essential to infer the conditions that contributes to the formation of archaeological sites in general. The stone tools are the material sign from which can begin the study of site formation processes and their behavior on archaeological record by experimental analogue. Thus, the objective of this study was to deepen the knowledge about these processes and their actions on the use traces found in lithic artifacts recovered from the Maripe Cave (Santa Cruz, Argentina) archaeological site with human occupations since early Holocene. The action of water as modifying agent may have influenced the changes of the surfaces and edges of stone tools, affecting differentially the conservation degree of micro-wear traces in different sectors of the cave. To assess the functional variability of artifacts, we present the results applying two independent studies: functional and diatom analysis.

          Toward the Identification of Formation Processes

          Research in experimental archaeology, ethnoarchaeology, geoarchaeology, and vertebrate taphonomy has appreciably increased our general understanding of the formation processes—cultural and natural—of archaeological sites. In synthesizing some of these recent advances, this paper focuses on the traces of artifacts and characteristics of deposits that can be used to identify the formation processes of specific deposits. These observational phenomena are grouped into three basic categories that structure the presentation: (1) simple properties of artifacts, (2) complex properties of artifacts, and (3) other properties of deposits. Also considered is the way in which prior knowledge can help the archaeologist to cope with the large number of processes and the nearly infinite combination of them that may have contributed to the specific deposits of interest. Several analytical strategies are proposed: (1) hypothesis testing, (2) multivariate analysis, and (3) use of published data to evaluate formation processes. This paper demonstrates that the identification of formation processes, which must precede behavioral inference and be accomplished by any research endeavor that uses evidence from the archaeological record, can become practical and routine.
