SCHEIFLER, Nahuel; MESSINEO, Pablo  and  ANTINIR, Ailén. HUNTER-GATHERERS IN THE HINOJO-LAS TUNAS SHALLOW LAKE SYSTEM (PAMPEAN REGION-WEST AREA) DURING EARLY/MIDDLE AND LATE HOLOCENE. FIRST RESULTS OF ARCHAEOLOGICAL RESEARCH. Comechingonia [online]. 2017, vol.21, n.1, pp.1-10. ISSN 1851-0027.

This paper reports the state of the progress in the archaeological investigations in the Hinojo-Las Tunas Shallow Lake System (West area of the Pampa region). The main characteristics of the environmental scenario is defined and the first results of the different research lines studied in the La Susana 1 and Huencú Nazar archaeological sites are presented, which include chronological, geological, technological, subsistence and mobility and settlement strategies analysis. These sites represent hunter-gatherer occupations located in the Early-Middle Holocene boundary (La Susana 1) and Late Holocene (Huencú Nazar). They are located in sectors with fresh water sources, which are heterogeneously distributed in the landscape and time, according to the cycles of excess and water deficit that characterize the current climate of the Pampas region. In this way, the existence of changes in the intensities of the human occupations in the Hinojo-Las Tunas Shallow Lake System during the Holocene wet and arid paleoclimate periods is considered. The lithic technology analysis allows us to argue that the population dynamics in this shallow lake system involved several spatial vectors (i.e. south, north, west and east). Finally, the study of archaeofaunas shows an economy oriented to the exploitation of guanaco (Lama guanicoe).

Keywords : pre-hispanic indigenous occupations, archaeological information, adaptation strategies, mobility, technology.
