PREHISTORIA DEL PERíODO FORMATIVO EN LA CUENCA ALTA DEL RíO SALADO (REGIóN DEL LOA SUPERIOR)

the systematization on chronology, rock art, landscape, and settlement pattern carried out at the upper salado river in the loa superior basin have produced important advance in the understanding of the regional prehistory. this is particularly true for the formative and early intermediate periods as multiple archaeological settlements have been identified, supported by more than forty archaeometric from 1.400 bc to ad 900. these results have permitted to go ahead in the comprehension of the subsistence and settlement systems of the local populations, and to understand their entailment with the complex formative processes that are developing in the circumpunean. in this paper, a specifically cultural/historical period frame for the formative period is proposed throughout a systematization of settlement and chronology's new information in this sub-region, updating previous chronological data and integrating the whole archaeological information
