La organización de la tecnología lítica en el noroeste argentino. Aproximación a través de experimentación, análisis tecno-morfológico y de microdesgaste por uso de palas y/o azadas líticas.

The investigation is aimed on the production, variability and change of lithic shovels and/or hoes from the northwest of Argentina . The approach is carried out from the technological organization perspective with the purpose of analyzing the technological strategies involved in the process of transition from Early husbandry societies to those with productive economies developed during the later moments.A research design that approaches the study through diverse analysis lines is used, considering: a) technic-morphological and morphological-functional analysis of artefactual assemblages from sites with differential distribution and chronology, b) Experimental Program to the replication of diverse production stages and use of artefacts, and c) use wear analysis in both collections: the archaeological and the experimental one.
