Support for the Archaeometry Laboratory at MURR

在美国国家科学基金会的支持下，迈克尔·科洛姆科克博士和他的同事们将继续在密苏里州大学研究反应堆中心（穆尔）的考古实验室工作。穆尔考古实验室是美国最全面的实验室之一，致力于考古材料的化学表征研究。穆尔提供的分析技术包括中子活化分析（NAA）、使用高分辨率和四极杆仪器对溶液进行电感耦合等离子体质谱（ICP-MS）、激光烧蚀ICP-MS（LA-ICP-MS）以及常规和便携式XRF。这些多分析/多元素技术允许在广泛的考古材料中同时定量主要、次要和痕量元素，并且具有相当的准确性和精确性。 穆尔设施在培训学生了解将特定分析技术应用于考古问题的优点和缺点方面也发挥着重要作用。 经常，考古学学生被邀请花时间在现场参观密苏里州实验室，在那里他们被教导各种方法来解释考古数据，并直接访问大型组成数据库，其中包含超过70，000个以前的分析陶器，黑曜石，燧石由INAA。 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。除了继续支持学生和高级考古学研究项目外，Dr. Reyncock还将致力于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）。这项工作将有利于新的和成熟的分析程序参与考古成分分析研究。Dr. Reyncock和他的同事还将继续监督LA-ICP-MS在考古材料中的开发和应用，并将促进便携式XRF在考古研究中的发展。 这笔赠款的更广泛影响是，与同事和学生合作产生的基本数据将继续用于解决与过去人类和社会动态有关的重要问题，例如人口流动模式和迁移、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。成分数据还可以提高对古代技术的理解，并（通过对骨骼遗骸的分析）可以深入了解史前饮食和营养。

With National Science Foundation support Dr. Michael Glascock and his colleagues will continue the operation of the Archaeometry Laboratory at the University of Missouri Research Reactor Center (MURR). The MURR Archaeometry Laboratory is one of the most comprehensive US-based laboratories dedicated to chemical characterization studies of archaeological materials. The analytical techniques available at MURR include neutron activation analysis (NAA), inductively-coupled-plasma mass-spectrometry (ICP-MS) of solutions using high resolution and quadrupole instruments, laser ablation ICP-MS (LA-ICP-MS), and conventional- and portable-XRF. These multi-analytical/multi-elemental techniques permit the quantification of major, minor and trace elements simultaneously and with considerable accuracy and precision in a wide range of archaeological materials. The MURR facility also plays an important role in training students in the advantages and disadvantages of applying specific analytical techniques to archaeological questions. Frequently, archaeology students are invited to spend time on site visiting the Missouri laboratory where they are taught a variety of methods for interpreting archaeological data and have direct access to the large compositional databases containing more than 70,000 previous analyses of pottery, obsidian, and chert by INAA. Online access to these databases is continuing to be developed and improved for integration with databases from other laboratories. In addition to continued support of student and senior archaeology research projects, Dr. Glascock will also work toward the development of calibration standards and analytical procedures that facilitate the integration of data from multiple analytical techniques (e.g., INAA, ICP-MS, XRF). This effort will benefit both new and mature analytical programs involved in archaeometric compositional analysis research. Dr. Glascock and his colleagues also will continue to oversee the development and application of LA-ICP-MS to archaeological materials and will facilitate the development of portable-XRF for archaeometric research. The broader impacts of this grant are that elemental data generated in collaboration with colleagues and students will be continue to be used to address important topics related to past human and social dynamics, 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. Compositional data also can improve understanding of ancient technologies and (through analysis of skeletal remains) can provide insight into prehistoric diet and nutrition.
