Comparative Analysis of Glacial Sediments, Minnesota and Brazil

在这个项目中，8名女性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和巴西圣保罗州西部晚古生代冰川沉积物的起源。该研究项目将建立在一个长期运行的REU项目的基础上，该项目基于明尼苏达大学莫里斯分校（UMM）和圣保罗大学（USP）师生之间长期建立的合作研究成果。在明尼苏达州，这包括继续密切相关的项目，这些项目共同利用till分析来确定问题沉积物的起源和冰川历史，包括隧道谷Eskers，条纹和多面巨石路面以及冰川湖Benson的各种沉积物。在巴西，第四纪和古生代沉积物（二晶岩和变岩）和特征（岩屑、巨石路面和楔型铸件）的对比分析使人们能够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.
