Laboratory Support for the Laboratory for Archaeological Chemistry

在国家科学基金会的支持下，威斯康星大学麦迪逊分校的T.Douglas Price博士和James Burton博士，以及北卡罗来纳大学教堂山分校的Paul Fullager博士，继续进行考古化学实验室的研究，这是美国为数不多的进行此类研究的机构之一。这笔资金以实验室支助奖的形式，将允许实验室继续研究过去人类迁徙和居住变化的同位素测量。该实验室的主要重点之一是将锶和铅同位素应用于过去人类活动的问题。这一密集的重点涉及描述威斯康星州、洪都拉斯和德国三个不同地点锶同位素比率的局部变化，以确定锶的来源并提高我们识别移民的能力。对这些地点的同位素的初步研究记录了在场人员的流动性，以及埋在地下的居民之间的巨大差异。这里提出的详细研究将为该遗址居民所利用的锶的来源提供新的见解。这些新信息将告诉我们社区内饮食的年龄/性别差异和景观的使用(例如，农田、夏季牧场和狩猎区)，并提供急需的当地变化范围的确定。该项目将导致在考古研究中使用同位素探明的新方法，这将提供有关过去人类利用这一景观的新信息。这些信息对理解过去向农业的过渡和文化变化的性质具有重要意义。是人类迁徙在史前农业、语言和遗传物质的传播中发挥了重要作用，还是当地群体从外来者那里吸收了农业知识和材料？这项研究是考古学中同位素探明研究的前沿。这项研究产生的新视角和新技术无疑将产生新的知识。科学界和整个社会将感受到更广泛的影响。考古化学实验室以教育和化学分析的形式向考古界提供服务，涉及全球各地的机构和同事。一般而言，这些活动和拟议的项目特别让学生和同事参与考古学和生物考古学中考古测量方法的开发和应用。这些活动的范围是国际性的，影响到相当数量的学生和同事。

With National Science Foundation support, Dr. T. Douglas Price and Dr. James Burton of the University of Wisconsin-Madison, along with Dr. Paul Fullager (University of North Carolina-Chapel Hill), with continue the investigations of the Laboratory for Archaeological Chemistry, one of the very few institutions for such research in the US. This funding, in the form of a Laboratory Support Award, will permit the laboratory to pursue the study of isotopic measures of past human migration and residence change. One of the major foci of the lab is the application of strontium and lead isotopes to questions of human movement in the past.This intensive focus involves the characterization of local variation in strontium isotope ratios at three separate localities in Wisconsin, Honduras, and Germany to determine sources of strontium and improve our ability to identify migrants. Preliminary studies of isotopes at these sites have documented the mobility of individuals present, as well as substantial variation among the buried inhabitants. The detailed studies proposed here will provide new insight into the sources of strontium utilized by the inhabitants of the site. This new information will tell us about age/sex differences in diet within the community and the use of the landscape (e.g., agricultural fields, summer pasture, and hunting areas), as well as providing a badly needed determination of the local range of variation. This project will result in new approaches to the use of isotopic proveniencing in archaeological studies that will provide new information on the human use of the landscape in the past. This information has important implications for understanding the transition to agriculture in the past and the nature of culture change. Did human migration play a major role in the spread of prehistoric agriculture, language, and genetic material, or did local groups adopt the knowledge and materials of farming from outsiders? This research is new and at the cutting edge of isotopic proveniencing studies in archaeology. New perspectives and new techniques resulting from this study will undoubtedly produce new knowledge. Broader impacts will be felt on the scientific community and society at large. The Laboratory for Archaeological Chemistry provides a service to the archaeological community in the form of education and chemical analyses that involves institutions and colleagues around the globe. These activities in general and the proposed project specifically involve students and colleagues in the development and application of archaeometric methods in archaeology and bioarchaeology. These activities are international in scope and affect substantial numbers of students and colleagues.
