Cronología del Periodo Medio en el Valle de Azapa, Norte de Chile: Estilos, Fechados y Contextos Culturales del Poblamiento Humano

A new analysis of 116 radiometric dates from the Azapa Valley, Chile, challenges the long-held association between Tiwanaku influence and the Middle Period (500–1000 AD). Contrary to previous assumptions, late ceramic styles linked to Tiwanaku (900–1100 AD) were not dominant in earlier centuries. Instead, local agricultural traditions persisted from the Formative period through the 8th century, with a distinct Phase II emerging around 500 AD characterized by Cabuza, Maitas, and Chiribaya styles. This phase suggests the development of a regional identity, culminating in the Arica Culture during the Late Intermediate Period (LIP). The study used Carbon-14 (C14) and thermoluminescence (TL) dating from nine cemeteries to refine chronological frameworks and redefine cultural continuity in the region.
