Comparison of Geology and Magnetism of a Portion of the Thunder Bay and Rainy River Districts
The portion of the Thunder Bay and Rainy River Districts covered in this report is an area of greatly varying magnetic susceptibility. Comparison of the geology and magnetic susceptibility by use of transparent overlays displays various features not previously shown on conventional geologic maps. Tw...
