Low-level airplane flights kave begun over the Duluth Complex and Cuyuna Range in Northeastern Minnesota to image geology using airborne geophysical technology. The flights are a collaborative effort between the U.S. Geological Survey’s Earth Mapping Resources Initiative and the Minnesota Geological Survey and are part of a national effort to modernize mapping of the nation’s geology. “Partnership with state surveys helps accomplish national goals like mapping the critical minerals the U.S. needs. It accelerates our ongoing mission to provide the geologic information necessary to protect and manage mineral and water resources across the state,” said Robert Tipping, Director of the Minnesota Geological Survey. This effort is known as the Earth Mapping Resources Initiative, and it includes airborne geophysical surveys like this one, geochemical reconnaissance surveys, topographic mapping using LiDAR technology, hyperspectral surveys, and geologic mapping projects.
