U.S.-Argentina Cooperative Research: Holocene Taphonomy, Landscapes & Geochronology of the Rio Quequen Middle Basin on the Pampas of Argentina

9603078 Johnson这个美洲项目奖将资助德克萨斯州理工大学的Eileen Johnson博士和Dr. Johnson博士之间为期两年的合作研究项目。Gustavo Politis，国立拉普拉塔大学，阿根廷，Jose Prado，国立布宜诺斯艾利斯中央大学。他们将研究在阿根廷潘帕斯草原的大皇后盆地中部建立第四纪考古遗址的地语学过程，目的是增加史前人类生存和土地利用的数据库。建议的工作重点是分析从这些地点恢复的改良和未改良的骨头。为了确定它们的类型和来源，我们将在显微镜下、光显微镜下和扫描电子显微镜下研究这些变化。基于对骨骼材料、埋藏土壤和放射性碳定年的分析，研究人员将试图描绘出遗址工作的形成和干扰过程、人口的生存基础和社会结构，以及他们职业的环境和气候背景。该项目将促进对全新世中晚期草原环境适应的比较认识。在创造考古记录的过程中，湖沼过程和人类活动之间的联系对我们理解早期的职业至关重要。计划中的古地貌重建将对该地区的地质考古学作出重大贡献。* * *

9603078 Johnson This Americas Program award will fund a 2-year cooperative research project between Dr. Eileen Johnson, Texas Tech University, and Drs. Gustavo Politis, Universidad Nacional de La Plata, Argentina, and Jose Prado, Universidad Nacional del Centro de la Provincia de Buenos Aires. They will study the taphonomic processes involved in the creation of Quaternary archaeological sites in the middle basin of the Rio Quequen Grande in the Argentinean Pampas, with the goal of increasing the database on prehistoric human subsistence and land use. The proposed work focuses on the analysis of modified and unmodified bone recovered from the sites. Modifications will be studied on microscopic, light microscopic, and scanning electron microscopic levels in order to determine their type and source. Based on the analysis of the bone material, buried soils, and radiocarbon dating, the researchers will try to delineate the formative and disturbances processes at work at sites, the subsistence base and social structure of the population, and the environmental and climatic setting of their occupations. The project should advance the comparative understanding of Middle to late Holocene adaptations to grasslands environments. The linkage among limnological processes and human activity in the creation of the archaeological record is crucial to our understanding of early occupations., and the planned reconstruction of the paleolandscapes will constitute a major contribution to the geoarchaeology of the region. ***
