Fifteen years ago, our research team started to carry out multi-proxy analysis in several sedimentary deposits from the Tropical Andes Highlands of Jujuy with different chronologies. These studies have furthered our knowledge about paleoenvironmental conditions and their variability over the last 13 Kyrs. at different time-space scales. Most of them were framed in a broader paleoecological research agenda focused on disentangling the complex nature of the relationship between the environment and human populations in the past. The obtained data have permitted us to set the ecological basis for building several archaeological models about different organizational issues of human groups. In this poster we present the first results of our analysis of diatoms and organic matter (OM) content in Cruces Core 1, one of the paleoenvironmental records currently under study by the research team.
