Peterson_Photo_WSU (1)Winona State University’s Department of Geoscience will host “Linking Antarctic & Minnesota Geology: Bringing Knowledge Gained at 100% Exposure Back to the North Woods” with Dean Peterson at 4 p.m., Monday, March 28, in the Science Laboratory Center 120 as part of the Earth Talks Series.

Peterson will talk about how the understanding of northeastern Minnesota’s Duluth Complex bedrock geology is hindered by many factors, and about how these issues have led to scattered knowledge of how such systems form and what they truly are.

Peterson will also cover the most revealing means of understanding magmatic systems such as the End Member Magmatic Analog, the Ferrar Dolerites, and Dry Valleys of Antarctica.

Peterson is the principal at Peterson Geoscience LLC and Co-Director of the Precambrian Research Center at the University of Minnesota-Duluth. He was the Senior Vice President-Exploration for Duluth Metals from 2008 to 2015 and discovered the extension of the Maturi Cu-Ni-PGE deposit in the Duluth Complex. He has over 30 years’ experience in mineral exploration, geological consulting, and developing economic geology research programs.

This event is free and open to the public.

Earth Talks Speaker Series is hosted each semester by the Geoscience Department. The series serves as a forum through which experts from academia, government and the private sector, as well as WSU students and faculty, share their experiences and research results with the WSU geoscience community. The series also provides a venue for discussions of professional, educational, and employment issues related to geology, natural resources, Earth science teaching, and other related disciplines.
