Condiciones climáticas y ambientales durante el primer milenio de la era en el Valle de Tafí (Tucumán, Argentina)

Abstract

This paper is aimed to recognize climatic and environmental conditions prevailing during the main occupation of La Bolsa 1 archaeological site (ca. 200 BC-900 AD) through palynological analysis of archaeological soil samples taken from agricultural structures. During the period studied, the vegetal communities which had developed in the Tafivalley suffered local variations, as a consequence of alternating dry and humid periods, the last ones possibly coincided with the introduction of agriculture in the region. Recognized vegetal communities did not show evidences of human effects (v.g. maize pollen grains). © 2013 by the Sociedade Brasileira de Paleontologia.
