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...

Comparison of the geology and magnetic susceptibility by use of transparent overlays displays various features not previously shown on conventional geologic maps. Two subparallel magnetic highs trending at essentially right angles to the regional trends are strongly suggestive of dikes of basic rock. Small isolated highs in the western portion of the map are interpreted to be stocks of highly magnetic rock. The magnetic anomaly crossing batholithic granite indicates a continuation of Keewatin strata though not mapped. Likely locations of gold, nickel and iron concentrations are exhibited.
