9322112 Cotter Ten women will be involved in field and laboratory research to determine the origin of glacial and postglacial deposits in west- central Minnesota. This includes the continuation of three closely related projects which have in common the utilization of till provenance analysis to determine the origin and glacial history of three problematic deposits. These deposits are, 1) the Alexandria Moraine Complex, 2) Tunnel Valley Eskers, and 3) the striated and faceted Boulder Pavement of the Minnesota River Valley. Additionally, paleoenvironmental studies of lacustrine deposits will be expanded and will include micropaleontological, palynological and geochemical investigations. U.M.M., an undergraduate institution, offers excellent facilities and close faculty contact. R.E.U. women will have the opportunity to develop collegial ties with other undergraduates doing geologic research and to serve as mentors, instructors and role models to underrepresented high school students participating in college level research. The research experience and the unique opportunity to interact with a scientific community when underrepresented individuals are in the majority will both break down a number of traditional barriers and aid in the maturation of these students as scientists. The culmination to the program, the "Friends of UMM REU" conference, will provide these women with the opportunity to present results and discuss ideas with experts in the field. Additionally a field trip to the Canadian Rockies will show participants active glacial processes and glacial environments. The REU program will contribute to the personal growth of these women and the research to be accomplished will contribute to the understanding of the glacial history of Minnesota.

小行星9322112 10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冰川和冰后期沉积物的起源。 这包括继续进行三个密切相关的项目，这些项目的共同点是利用冰碛物源分析来确定三个有问题的沉积物的起源和冰川历史。 这些沉积物是，1）亚历山大冰碛复合体，2）隧道谷埃斯克斯，和3）明尼苏达河谷的条纹和刻面巨石路面。 此外，将扩大湖泊沉积物的古环境研究，包括微体古生物学、孢粉学和地球化学调查。 嗯，一所本科院校，提供一流的设施和密切的教师联系。 R.E.U.妇女将有机会与从事地质研究的其他大学生建立学院关系，并为参加大学研究的人数不足的高中生担任导师、指导员和榜样。 研究经验和独特的机会，与科学界互动时，代表性不足的个人是大多数都将打破一些传统的障碍，并在这些学生作为科学家的成熟援助。 该方案的高潮是“UMM REU之友”会议，将为这些妇女提供展示成果和与该领域专家讨论想法的机会。 此外，加拿大落基山脉的实地考察将向与会者展示活跃的冰川过程和冰川环境。 REU计划将有助于这些妇女的个人成长和研究完成将有助于明尼苏达州的冰川历史的理解。
