In response to the recent increase in exploration activity in the Duluth Complex, the Minnesota
Geological Survey (MGS) has released its preliminary gravity and magnetic grids for the Duluth
Complex of northeastern Minnesota and adjacent areas. Besides MGS data, the grids incorporate data
produced by the Wisconsin Geological and Natural History Survey, the U.S. Geological Survey, the
National Geophysical Data Center, and the Geological Survey of Canada. The grids are being used as
part of a ongoing study funded by the Minnesota Legislature through the Minnesota Minerals
Coordinating Committee. Users are warned that the grids are subject to minor revision.
PDF file contains metadata of data sets, .zip file contains grids of aeromagnetic data collected in the survey, and the .txt file contains descriptions of the grids and metadata.
