Support for the Archaeometry Laboratory at MURR

在国家科学基金会的支持下，密苏里州大学研究反应堆中心（穆尔）的考古实验室将继续作为美国最全面的实验室，致力于考古材料的化学表征研究。可用的分析技术包括中子活化分析（NAA）、使用高分辨率、四极杆和多集电极仪器的溶液的电感耦合等离子体质谱（ICP-MS）、激光烧蚀ICP-MS（LA-ICP-MS）和X射线荧光（XRF）。这些技术可以同时对大量考古材料中的主要、次要和微量元素进行定量，并具有高度的准确性和精确性。穆尔实验室在培养学生应用于特定考古问题的分析技术方面也发挥着重要作用。经常，考古学学生被邀请花时间在穆尔，在那里他们被教导了各种方法来解释考古数据，并直接访问包含超过130，000个以前的陶器，黑曜石，玄武岩和燧石分析的大型成分数据库。正在继续开发和改进这些数据库的在线访问，以便与其他实验室的数据库相结合。实验室工作人员和学生也参与了从不再运行的实验室中抢救成分数据库的工作。世界上许多地方的陶瓷数据库已经达到了足够的规模，可以进行区域综合，研究大规模的陶瓷生产，使用和交换模式。除了继续支持学生和高级考古研究项目外，资金还有助于支持校准标准和分析程序的开发，以促进多种分析技术（例如，INAA、ICP-MS、XRF）。这些努力将有利于新的和成熟的分析程序参与考古成分分析研究。Ferguson和Albercock继续监督LA-ICP-MS在考古材料中的开发和应用，并促进便携式XRF在考古研究中的发展。这项工作的更广泛的影响包括与同事和学生合作产生的基本数据，这些数据将用于解决与史前人民和社会的人类和社会动态有关的重要主题，例如人口的流动模式和迁移，对冲突和压力的文化反应，社区社会组织，手工艺生产和专业化的发展，以及社会边界和身份的建立和维护。

With National Science Foundation support the Archaeometry Laboratory the University of Missouri Research Reactor Center (MURR) will continue to serve as the most comprehensive US-based laboratory dedicated to chemical characterization studies of archaeological materials. The analytical techniques available include neutron activation analysis (NAA), inductively-coupled-plasma mass-spectrometry (ICP-MS) of solutions using high resolution, quadrupole, and multicollector instruments, laser ablation ICP-MS (LA-ICP-MS), and X-ray fluorescence (XRF). These techniques permit the quantification of major, minor and trace elements simultaneously and with a high degree of accuracy and precision in a wide range of archaeological materials. The MURR laboratory also plays an important role in training students in the analytical techniques for application to specific archaeological questions. Frequently, archaeology students are invited to spend time at MURR where they are taught a variety of methods for interpreting archaeological data and have direct access to the large compositional databases containing more than 130,000 previous analyses of pottery, obsidian, basalt, and chert. Online access to these databases is continuing to be developed and improved for integration with databases from other laboratories. Laboratory staff and students are also involved in efforts to rescue compositional databases from laboratories no longer in operation. The ceramic databases in many parts of the world have reached a sufficient size to allow regional syntheses that examine large-scale patterns of ceramic production, use and exchange.In addition to continued support of student and senior archaeology research projects, funding helps support the development of calibration standards and analytical procedures that facilitate the integration of data from multiple analytical techniques (e.g., INAA, ICP-MS, XRF). These efforts will benefit both new and mature analytical programs involved in archaeometric compositional analysis research. Ferguson and Glascock continue to oversee the development and application of LA-ICP-MS to archaeological materials and facilitate the development of portable-XRF for archaeometric research. The broader impacts of this work includes the elemental data generated in collaboration with colleagues and students that will be used to address important topics related to human and social dynamics of prehistoric peoples and societies, such as, mobility patterns and migrations of people, cultural responses to conflict and stress, community social organization, the development of craft production and specialization, and the creation and maintenance of social boundaries and identity.
