Análisis de microvestigios en pipas procedentes de ocupaciones prehispánicas de las selvas meridionales del noroeste Argentino. El caso de Yánimas 1

Abstract

In this paper we expose the results obtained from the residues analysis in ceramic pipe's fragments recovered from mound elevation 1 (EM1) and 3 (EM3) at the site, Yánimas 1. To carry out this study we performed the preparation of samples from the residues taken from the pipe fragments (suction pipes and stove pipes in the case of Sample F for the sector EM 3) in order to observe them at petrographic microscope. We compared the results with the current botanical reference material. In this way it was possible to make some taxonomic inferences of the observed microremains. This methodology threw positive results for residues showing the presence of starch grains simile to Nicotiana spp. and starch grains and calcium phytoliths possibly ascribed to Anadenanthera colubrina var. cebil (Griseb.) Altschul. Through this analysis we could discuss new data regarding the use of pipes and consumption of entheogenic plants in Tucumán's piedmont, at late first millennium AD.
