MEDINA, Matías E.; GRILL, Silvia C.  e  LOPEZ, M. Laura. Archaeological Palynology: Its Impact On The Study Of The Late Prehispanic Period Of The Sierras De Córdoba, Argentina. Intersecciones antropol. [online]. 2008, n.9, pp.99-112. ISSN 1850-373X.

Four archaeological sites dating from the Late Prehispanic Period of the Sierras de Córdoba (ca. 1000-300 BP) are studied by means of palynological analysis. These sites are Los Algarrobos 1, Puesto La Esquina 1 (Pampa de Olaen), C.Pun.39 and Las Chacras 2 (Punilla valley). Los Algarrobos 1 and Puesto La Esquina 1 sites present scarce pollinic grains as a consequence of taphonomic bias. However, from the pollinic spectrum from C.Pun.39 and Las Chacras 2 sites it was possible to infer vegetational paleo-communities dominated by Chenopodiaceae- Amaranthaceae and Brassicaceae (at C.Pun.39 site) and by the former taxon (at Las Chacras 2 site). There is poor presence of both vegetable families in current pollinic samples. It is thought that the high proportions of Chenopodiaceae- Amaranthaseae might suggest the presence of pre-Hispanic Chenopodium quinoa and Amaranthus caudatus crops in the areas surrounding the sites. Further evidence, such as domestic plant remains and agricultural tools, supports this hypothesis. Nevertheless, the high proportions of Chenopodiaceae-Amaranthaceae and Brassicaceae found in C.Pun.39 would also indicate successive abandonment and reoccupation processes at the residential camps, probably seasonally. Environments affected by anthropic activity might have contributed to the growth of these plants.
