Arqueología y ambiente en un valle intermontano del piedemonte oriental de las Cumbres Calchaquíes (Tucumán, Argentina)

in the last decade, for the archaeology of tucumán, many studies about paleoenvironmental conditions during prehispanic occupations have been taken place. these studies were focused mainly at the valley of tafí, archaeological area of one of the first socio-cultural developments in the noa. the knowledge of the paleoenvironment allows the elaboration of more reliable archaeological contexts. in this work we make an approximation for two temporal-spatial moments in the archaeology of a sector at the eastern cumbres calchaquíes piedmont. for this, we analyze two archaeological sites and their paleoenvironmental contexts, using proxy derived of the stratigraphy, the sedimentology and the palinology. these proxies allows the determination of some variations in the ambiental humidity, this situation is reflected in the polinic record and in the pedogenetic cycles of the analyzed moments.
