Comparative Analysis of Glacial Sediments, Minnesota and Brazil

-在这个项目中，8名妇女将参与野外和实验室研究，以确定明尼苏达州中西部第四纪冰川沉积和巴西圣保罗州西部晚古生代冰川沉积的来源。该研究项目将建立在UMM的长期REU项目和明尼苏达大学莫里斯分校(UMM)和圣保罗大学(USP)教职员工和学生之间的长期合作研究成果的基础上。在明尼苏达州，这包括继续开展密切相关的项目，这些项目的共同点是利用TIL分析来确定问题沉积物的来源和冰川历史，包括隧道谷Eskers、有条纹和多面的Boulder路面以及冰川湖本森湖的各种沉积物。在巴西，对第四纪和古生代沉积物(透长岩和杂岩)和特征(角砾岩、巨石路面和楔形铸造物)进行对比分析，可以深入了解古环境的冰川历史。

--In this project, eight women will be involved in field and laboratory research to determine the origin of glacial deposits of Quaternary age in west-central Minnesota and late Paleozoic age in western Sao Paulo state, Brazil. This research program will be founded upon a long-running REU program based at UMM and a long-established collaborative research effort between the University of Minnesota, Morris (UMM) and Universidade de Sao Paulo (USP) faculty and students. In Minnesota, this includes the continuation of closely related projects that have in common the utilization of till analysis to determine the origin and glacial history of problematic deposits including Tunnel Valley Eskers, a striated and faceted Boulder Pavement and varied sediments of Glacial Lake Benson. In Brazil, comparative analysis of Quaternary and Paleozoic sediments (diamictites and varvites) and features (eskers, boulder pavements and wedge casts) allows insight into the glacial history of paleoenvironments.
