    dct:description "New gravity and magnetic compilations and elevation-bathymetry models have been compiled for the Lake Superior region. These data provide continuous sets of observations for geologic interpretations spanning political boundaries such as US States and the US-Canada border where bedrock geology is largely concealed beneath glacial deposits and surface water. These data are providing constraints for on-going 3D geologic modeling of the Midcontinent Rift System and are helping to understand the metallogeny of the region." ;
