EAR-PF: Evaluating Strain Localization, Melt Localization, and Mantle Rheology in the Twin Sisters Ultramafic Body, Washington: A Multi-Scale Approach

塞思·克鲁肯伯格博士被授予美国国家科学基金会地球科学博士后奖学金，在威斯康星大学麦迪逊分校开展研究和教育项目。克鲁肯伯格博士将利用在孪生姐妹基性地块中观察到的不同成分（如熔融路径、剪切带以及富含橄榄石和橄榄石+辉石的岩石的成分变化），创建岩石圈地幔成分、结构和应变非均质性的定量模型。这项研究的结果将具有广泛的构造意义，并提供有关自然变形的地幔的信息，以及上地幔熔体分离和变形分配的动态反馈信息。此外，克鲁肯伯格博士将把这项研究与本科阶段的三项教育活动结合起来。首先，他计划指导两名本科生进行高级研究项目。其次，作为他职业发展的一部分，克鲁肯伯格博士还计划参加美国国家科学基金会赞助的研究、教学和学习整合中心（三角洲计划），该中心位于威斯康星大学麦迪逊分校。第三，为了最大限度地发挥这项研究的科学成果的影响，他将与Basil Tikoff博士（赞助科学家）一起开发一个教学模块，该模块将在变质地体实地调查的背景下告知这项研究的结果。

Dr. Seth Kruckenberg is awarded an NSF Earth Science Postdoctoral Fellowship to carry out a program of research and education at the University of Wisconsin - Madison. Dr. Kruckenberg will create quantitative models of compositional, fabric, and strain heterogeneities in the lithospheric mantle using different components observed in the Twin Sister mafic massif (like melt pathways, shear zones, and compositional variations of olivine rich and olivine+pyroxene rich rocks). The results from this investigation will be of broad tectonic interest and provide information on the naturally deformed mantle, as well as inform on the dynamic feedbacks of melt segregation and deformation partitioning in the upper mantle.In addition, Dr. Kruckenberg will be integrating the research with three educational activities at the undergraduate level. First, he anticipates mentoring two undergraduate students in senior research projects. Second, as part of his career development, Dr. Kruckenberg also plans on participating in the NSF-sponsored Center for the Integration of Research, Teaching and Learning (Delta Program), which is based at the University of Wisconsin - Madison. Third, to maximize the impact of the scientific results of this study, he will develop a teaching module with Dr. Basil Tikoff (sponsoring scientist) that will inform of the results of this study in the context of field-based investigations of metamorphic terranes.
