Resumen

SOMONTE, Carolina  y  BAIED, Carlos A.. Palimpsests as a gateway to different temporalities: The case of Rio Las Salinas 2 (Tucuman, Argentina). Estud. atacam. [online]. 2017, n.55, pp.35-55.  Epub 03-Jul-2017. ISSN 0718-1043.  http://dx.doi.org/10.4067/S0718-10432017005000014.

In order to evaluate variability in land-use histories, in this paper we discuss the usefulness of the concept ofpalimpsest, a theoretical-methodological tool that can be used to analyze and decompose archaeological landscape structures into suitable analytical units. To do so, and through a case study: Rio las Salinas2, we assessed indicators of stability at both the landscape and artifact levels. At the landscape level, we took into account operating geomorphological processes, particularly desert pavement that supports surface lithic scatters. At the artifact level and through typological analysis of artifacts, we looked into the effects of post-depositional alterations in rocks (patinas, mechanical weathering-wind abrasion, cleavage, and refitting Research results suggest conditions of greater and lesser stability associated to desert pavement with varying degrees of maturity and on which natural processes occur shaping discovery conditions of the archaeological record. At one end, stability is associated to places where pavement shows a certain degree of preservation, with a correlate at scale of the artifact where the varnish of the rocks and the assembly ratify this stability. At the other end, we identified conditions of instability, marked by erosion processes within areas where the pavement is deteriorated or, where there is no pavement. Between these two ends, a variety of hues where we find evidence of both stability and instability at different scales mirroring the different conditions to which the artifacts were exposed to.

Palabras clave : Landscape stability; lithic artifact scatters; archaeology; geoarchaeology.
