This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). Research in Yellowstone National Park (YNP) will characterize the geology, geochemistry and geochronology of the Precambrian rocks that underlie the northern part of the Park. REU students will participate in three major activities that will constitute a complete research experience: 1) Field studies, conducted in YNP will include geologic mapping and sampling of the Precambrian basement of YNP; formulation of testable research questions by smaller working groups; and mapping and sampling projects to address these research questions; 2) Analytical studies, starting with sample preparation immediately following field work at Montana State University; petrographic analysis at the students' home institutions; a week-long visit to analytical laboratories to conduct follow-up studies by small research groups during the academic year (University of Florida for geochemistry and geochronology; Louisiana State University for electron microprobe analysis); 3) Communicating results, each working group will submit an abstract to the following Geological Society of America Rocky Mountain sectional meeting as a first step towards formalizing the research results, including a writing workshop to encourage collaborative writing towards a peer-reviewed journal article. This REU site project will be conducted over two years with a focus on the anomalously low-grade metasedimentary rocks in the first year and (meta)igneous rocks in the second year. In aggregate, the research results will provide important insights into the petrogenesis, architecture, and evolution of the Precambrian rocks of YNP.The research results will contribute to a more complete understanding of the natural history of YNP. The geologic maps and sampling locations will be GIS-based and will be transmitted to the YNP Research Office for inclusion in their database to help inform further research and management in YNP. Students who participate in this project will gain valuable research experience through participating in the full range of activities including hypothesis formulation and testing, field mapping and sampling, sample preparation, analytical studies on modern instrumentation, communicating results at a professional meeting and engaging collaborative writing towards a peer-reviewed journal article. A research on learning component will document the cognitive and affective impacts of the field experience on the participating students to help document best instructional practices in field instruction for use by the larger geoscience education community.

该奖项是根据2009年《美国复苏与再投资法》（公法111-5）资助的。黄石国家公园（YNP）的研究将描述公园北部底部的前寒武纪岩石的地质，地球化学和年代学。 REU学生将参加构成完整研究经验的三项主要活动：1）在YNP中进行的现场研究将包括YNP前寒武纪地下室的地质映射和采样；较小的工作组提出可检验的研究问题；以及映射和抽样项目以解决这些研究问题； 2）分析研究，从蒙大拿州立大学现场工作后立即进行样品制备开始；学生家庭机构的岩石学分析；在学年（佛罗里达大学的地球化学和地质学大学；路易斯安那州立大学电子微探针分析）进行了为期一周的分析实验室，以进行小型研究小组的后续研究； 3）沟通结果，每个工作组将向以下美国地质学会提交摘要，这是朝着正式化研究结果的第一步，包括一个写作研讨会，以鼓励协作写作对同行评审的期刊文章。该REU站点项目将在两年内进行，重点是第一年的低级岩石岩石，第二年（元）火成岩。总体而言，研究结果将为YNP前寒武纪岩石的岩化，结构和演变提供重要的见解。研究结果将有助于对YNP的自然历史有更全面的了解。地质图和采样位置将基于GIS，并将传输到YNP研究办公室，以纳入其数据库，以帮助YNP的进一步研究和管理信息。参加该项目的学生将通过参加包括假设的表述和测试，现场映射和抽样，样本准备，现代仪器的分析研究，在专业会议上传达成果的分析研究以及与同行评审的同行评审期刊文章的文章有关，将获得宝贵的研究经验。对学习组成部分的研究将记录现场经验对参与学生的认知和情感影响，以帮助记录大型地球科学教育社区使用的现场教学最佳教学实践。
