REU: Fluids in the Earth from Surface to Core

KOHLSTEDT9987969 REU站点涉及对地质流体的野外、分析、实验和理论研究。研究范围将从地表和近地表流体系统到地幔再到地核。每年将面向全国招收14名本科生。学生们将研究以地球流体为共同主题的主题。实习生将参与各种研究活动，包括人类活动对地下水质量的影响，主要是在岩溶和裂隙岩石含水层；通过盆地规模的水文地质模型研究流体在地壳过程中的作用；对湖泊进行边缘地质学研究，以了解区域环境动力学；评估变质和火成岩系统中流体的化学和机械影响；熔融对地幔岩石流变学的影响；以及利用科学可视化进行地幔对流和岩心动力学的数值实践经验。此外，他们还将通过参加中西部遗址(洞穴、冰川湖泊/河流地貌、中大陆裂谷熔岩)的实地考察，参观明尼苏达大学及其邻近地区的各种实验室设施(岩石磁学、同位素地球化学、岩石力学、电子显微镜)，以及参加大学暑期实习计划(化学、生物、物理、界面工程、环境科学)，接触到暑期研究之外的学科。

Kohlstedt9987969The REU Site involves a field, analytical, experimental, and theoretical study of geological fluids. Research will range from surface and near-surface fluid systems to the mantle to the core. Fourteen undergraduate students will be recruited nationally each year. The students will investigate topics with the common theme of fluids in the Earth. The interns will be involved in various research activities, including the impacts of human activities on groundwater quality primarily in karst and fractured rock aquifers, the role of fluids in crustal processes through basin-scale hydrogeologic modeling, limnogeology research on lakes to understand regional environmental dynamics, evaluation of the chemical and mechanical effects of fluids in metamorphic and igneous systems, the effect of melt on rheology of mantle rocks, and numerical hands-on experience with mantle convection and core dynamics using scientific visualization. In addition, they will be exposed to disciplines outside their summer research by participating in field trips to mid-western sites (caves, glacial lake/river features, mid-continent rift lavas), by touring a wide range of laboratory facilities (rock magnetism, isotope geochemistry, rock mechanics, electron microscopy) at the University of Minnesota and vicinity, and by taking part in university summer internship programs in a wide range of fields (chemistry, biology, physics, interfacial engineering, environmental sciences).
