Support for the Archaeometry Laboratory at MURR

在美国国家科学基金会的支持下。Michael Glascock和Jeffrey Ferguson将继续在密苏里大学研究反应堆中心（MURR）的考古实验室工作。考古测量实验室是美国最全面的实验室，致力于考古材料的化学表征研究，并因其在该领域的领导作用而在世界范围内得到广泛认可。可用的分析技术包括中子活化分析（NAA）、使用高分辨率、四极杆和多收集器仪器的溶液电感耦合等离子体质谱（ICP-MS）、激光烧蚀ICP-MS （LA-ICP-MS）以及传统和便携式xrf。这些技术允许在大量考古材料中同时定量主要、次要和微量元素，并具有高度的准确性和精密度。MURR实验室在训练学生运用分析技术解决具体考古问题方面也发挥着重要作用。考古学专业的学生经常被邀请到MURR学习各种解释考古数据的方法，并可以直接访问包含超过10万份以前对陶器、黑曜石、玄武岩和燧石的分析的大型成分数据库。正在继续发展和改进对这些数据库的联机访问，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拯救成分数据库的努力。世界许多地方的陶瓷数据库已达到足够的规模，可以进行区域综合，审查陶瓷生产、使用和交换的大规模模式。除了继续支持学生和高级考古研究项目外，Glascock和Ferguson还在开发校准标准和分析程序，以促进多种分析技术（例如，INAA, ICP-MS， XRF）数据的整合。这些努力将有利于考古成分分析研究中涉及的新的和成熟的分析程序。Glascock和Ferguson继续监督LA-ICP-MS在考古材料上的发展和应用，并促进用于考古研究的便携式xrf的发展。这项工作的更广泛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民族和社会的人类和社会动态相关的重要主题，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，工艺生产和专业化的发展，以及社会边界和身份的创造和维护。

With National Science Foundation support Drs. Michael Glascock and Jeffrey Ferguson will continue the operation of the Archaeometry Laboratory at the University of Missouri Research Reactor Center (MURR). The Archaeometry Laboratory is the most comprehensive US-based laboratory dedicated to chemical characterization studies of archaeological materials, and is widely recognized around the world for its leading role in the field. 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 conventional- and portable-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 100,000 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, Glascock and Ferguson are also developing 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. Glascock and Ferguson 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.
