Analysing geomorphology broadly and soils and sediments specifically are integral to understanding water and soil management in the Middle Preclassic around the site of Aguada Fenix, Tabasco, Mexico. This poster presents the soil and water chemistry of Aguada Fenix based on samples collected in 2018 in three main excavations. The laboratory analyses include soil and water elemental, compound, and mineral composition, as well as soil carbon isotopes and typical soil and sediment analyses. This is part of a broader project based in Anthropology at the University of Arizona that examines the origins of Mesoamerican Civilization. The parallel project presented here uses geoarchaeological and soil analysis to help understand the the Archaic and Preclassic evolution of water management and agriculture in this key region. This is a key region because of the early evolution of monumental architecture in this convergence zone of the great rivers of Mesoamerica, including Mexico’s largest river, the Usumacinta.
