La influencia de Tiwanaku en San Pedro de Atacama: Una investigación utilizando el análisis de isótopos del estroncio

The nature of Tiwanaku influence in the San Pedro de Atacama region during the Middle Horizon (AD 500-1000) has been widely debated. While some scholars have emphasized an indirect relationship based on religious and/or economic interactions, others have argues that a population of Tiwanaku colonists was physically present in San Pedro de Atacama. Here, strontium isotope analysis is used to identity the geographic origin of individuals buried in Coyo-3, Coyo Oriental and Solcor-3. This study identified no individuals who may have lived in the southeastern Lake Titicaca Basin during the first few years of their life, weakening the hypothesis that San Pedro de Atacama was a Tiwanaku colony.
