Abstract

The results are presented of the analysis of a set of 116 radiometric dates obtained through the method of Carbon 14 (C14) and thermoluminescence (TL) dating. These datings were taken from nine published studies carried out in the Azapa Valley. Regarding dated samples, these were mostly taken from burials (bodies) and offerings (ceramic) from cemeteries in the Azapa Valley linked to the Middle period. Chronologically this period has been associated with the presence of the Tiwanaku Horizon in the western valleys, 500 to 1000 AD, and its most representative feature is the presence of painted pottery with forms of keros, bowls, pucos and jars. However, the datings obtained for these ceramics mostly correspond to late datings within a range from Cal 900 to 1100 AD. On the other hand, recent information obtained from cemetery Az-115 on new dates indicates that in the first eight centuries of the first millennium of the Christian era there is no Tiwanaku presence in the Azapeño settlement, but rather a type of village continuity linked to a local history with roots in the Formative period.
