Past population dynamics in Northwest Patagonia: An estimation using molecular and radiocarbon data
(Academic Press Ltd - Elsevier Science Ltd, 2016-01)
Studying demographic changes in past human populations is of great interest due to their role in processes of cultural change as well as the biological evolution of populations. Despite this, a general consensus about the ...
Mid Holocene radiocarbon ages in the Subtropical Andes (~29° - 35° S), climatic change and implications for human space organization
(Elsevier, 2015)
This article discusses the distribution of radiocarbon age signatures obtained from archeological sites
between 29 and 35 S in Central Chile and Midwest Argentina. The goal of this analysis is to establish
bases from ...

Merging the Matrix: Stratigraphy, Radiocarbon Dates, and Fire Regimens in the Ambato Valley (Catamarca, NW Argentina)
(University of Arizona. Department of Geosciences, 2014-03)
This article compares radiocarbon dates and the stratigraphic matrix obtained from excavations at the Piedras Blancas archaeological site, Ambato Valley, NW Argentina. Analysis revealed inconsistencies between 14C dates ...
Chronology and human settlement in northeastern Patagonia (Argentina): patterns of site destruction, intensity of archaeological signal, and population dynamics
(Elsevier, 2013-03)
Temporal frequency distributions are used to assess the chronology and continuity of human occupation at different spatial scales, differential landscape use and demographic patterns throughout time. These issues were ...
Radiocarbon dates and anthropogenic signal in the South-Central Andes (12,500 - 600 cal. years BP
(Academic Press Ltd - Elsevier Science Ltd, 2016-01)
This paper presents the analysis of the anthropogenic signal documented by four time-series in the highlands of the South-Central Andes (Puna of Argentina and North Chile) spanning the period between 12,500 and 600 cal ...
Tree rings reveal globally coherent signature of cosmogenic radiocarbon events in 774 and 993 CE
(Nature Publishing Group, 2018-09)
Though tree-ring chronologies are annually resolved, their dating has never been independently validated at the global scale. Moreover, it is unknown if atmospheric radiocarbon enrichment events of cosmogenic origin ...
Annual nature of the growth rings of Araucaria araucana confirmed by radiocarbon analysis
(Elsevier, 2015-10)
During the late 1950s and early 1960s, thermonuclear tests added considerable amounts of 14C to the atmosphere. Since that time the amount has declined, which is owed to the exchange and dispersal of 14C into the Earth's ...
Demografía humana e incorporación de cultígenos en el centro occidente Argentino: Explorando tendencias en las fechas radiocarbónicasHuman demography and domestic plants in central Western Argentina: Exploring trends in radiocarbon dates
(Universidad Complutense de Madrid, 2015-06)
Clásicamente el origen y la dispersión de la agricultura se han explicado al menos parcialmente por variables demográficas. Este estudio, de carácter preliminar, explora el uso de la frecuencia de fechas radiocarbónicas ...
