We are working to return to in-person meetings, please watch for updates on future meetings.
NOTE: You Must Be Logged In to Register.
Speaker: Ben Drenth, US Geological Survey's Geology, Geophysics and Geochemistry Science Center in Denver, Colorado
The southern part of the Archean Superior Province in the Upper Peninsula of Michigan was a nexus for key Neoarchean and Paleoproterozoic tectonic events involved in the assembly and subsequent rifting of supercraton Superia, followed by complex orogenic processes related to the assembly of Laurentia. New aeromagnetic and gravity data provide a critical means of mapping and interpreting the complex geological framework through cover, allowing development of significantly richer geographical and process-based perspectives on all these tectonic events. This presentation will focus on recent USGS research along the southern margin of the Superior Province, as well as related topics of interest in the broader region.
