Summary

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.

Purpose

The purpose is to provide to the public updated compilations of gravity, magnetic, and topography-bathymetry data sets that span the Lake Superior region. The underlying data originate from disparate databases and have been brought together in a consistent manner using industry standard techniques. These data have a broad range of uses. In particular, they are proving useful for generating 3D geologic models of the Midcontinent Rift System.
