The sources of the anomalies in each of the blocks have not been identified definitely because of a lack of subsurface data, but are interpreted qualitatively from an analysis of the anomalies and considerations of the regional geology. An anomaly in the northwestern part of the county, near Hutchinson, is interpreted to represent a folded, magnetic rock unit. Probably this unit is a magnetite-bearing schist, but the possibility of its being an iron-formation of the Cuyuna-type should be investigated further.en-USReport
