--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.

--在这个项目中，8名妇女将参与实地和实验室研究，以确定明尼苏达州中西部第四纪冰川沉积物和巴西圣保罗州西部晚古生代冰川沉积物的起源。 该研究计划将建立在基于UMM的长期REU计划以及明尼苏达大学莫里斯分校（UMM）和圣保罗大学（USP）教师和学生之间长期建立的合作研究工作基础上。 在明尼苏达州，这包括继续进行密切相关的项目，这些项目的共同点是利用冰碛分析来确定有问题的沉积物的起源和冰川历史，包括隧道谷埃斯克斯、一个有条纹和刻面的巨石路面和本森冰川湖的各种沉积物。 在巴西，通过对第四纪和古生代沉积物（杂岩和蚀变岩）和特征（石砾、卵石铺层和楔形铸件）的比较分析，可以深入了解古环境的冰川历史。
