| Abstract: | A ground magnetometer survey of McLeod County, Minnesota
has delineated 3 structural blocks in the buried Precambrian
basement rocks. 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. |
