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年美国复苏和再投资法案（公法111-5）资助的。黄石国家公园（YNP）的研究将描述公园北方部分前寒武纪岩石的地质、地球化学和地质年代学特征。REU学生将参加三项主要活动，这些活动将构成完整的研究体验：1）在YNP进行的实地研究将包括YNP前寒武纪基底的地质测绘和采样;由较小的工作组制定可测试的研究问题;以及解决这些研究问题的测绘和采样项目; 2）分析研究，从蒙大拿州立大学野外工作后立即制备样品开始;在学生的家庭机构进行岩相分析;为期一周的访问分析实验室进行后续研究的小研究小组在学年（佛罗里达大学地球化学和地质年代学;路易斯安那州立大学电子探针分析）; 3）交流结果，每个工作组将向接下来的美国地质学会落基山分会会议提交摘要，作为正式确定研究结果的第一步，包括一个写作研讨会，以鼓励合作撰写同行评审的期刊文章。该REU现场项目将进行两年，第一年重点关注低品位变质沉积岩，第二年重点关注（Meta）火成岩。这些研究成果将为深入认识YNP前寒武纪岩石的成因、构造和演化提供重要的参考，有助于更全面地了解YNP的自然历史。地质图和取样地点将以地理信息系统为基础，并将传送给YNP研究办公室，以纳入其数据库，帮助YNP进一步的研究和管理。参加该项目的学生将通过参与各种活动获得宝贵的研究经验，包括假设制定和测试，实地测绘和采样，样品制备，现代仪器的分析研究，在专业会议上交流结果，并参与合作撰写同行评审的期刊文章。关于学习部分的研究将记录实地经验对参与学生的认知和情感影响，以帮助记录实地教学中的最佳教学实践，供更大的地球科学教育界使用。
