Thin section images of drill core and hand samples from the South Kawishiwi Intrusion, Duluth Complex, Minnesota

This dataset includes photographic images of thin sections created from hand samples and drill core sourced from the South Kawishiwi Intrusion, Duluth Complex, Minnesota, along with two shapefiles representing the locations of the samples and drill hole collars. The samples were collected and core was drilled in order to define copper-nickel-platinum-group element resources associated with the South Kawishiwi Intrusion in the Duluth Complex.
