Abstract:
The role of geoarchaeological studies in analyzing formation processes, chronology and paleoenvironmental conditions is considered in archaeological sites of southern Patagonia and Tierra del Fuego. On the basis of sensitivity to the appropriate scale, an archaeological perspective is offered. Sedimentary, pedological and geomorphic context are treated as important variables since they are related with different aspects of archaeological interpretation. If the archaeological record is spatially continuous, and its location in stratigraphy or on the surface is highly variable, particularly in relation with geomorphic variables, both situations need to be tackled for an integral approach. As an integrative aspect among the studied localities, the fieldwork have revealed the recurrent presence of a pedological event in the upper section of eolian and colluvial deposits of the late Holocene. Its temporal relationship with the medieval climatic anomalies called Medieval Warm Period or Medieval Optimum in Europe is suggestive. The distribution of artifacts in the soil profile shows a low frequency in its upper part, that is to say that, in spite of representing a stabilized surface during several centuries, it has not been a recipient of abundant archaeological material. That seems to suggest a greater human presence in these places at some time prior to the pedological development, during the predominance of the aridity conditions at regional scale. It can be speculated that changes occurring since those moments have affected the distribution and/or concentration of resources in the region, but it must be considered that the natural formation processes were also been affected, changing the resolution of the further record.
