| Abstract: | A magnetic anomaly centered at Lake Washington, in
southeastern Meeker County, has been outlined by a ground
magnetometer survey. The anomaly is arcuate in outline,
about 8.5 miles long and a maximum of 5 miles wide, and
has a maximum amplitude greater than 3,000 gammas. A
gravity traverse was made across the anomaly to aid in interpretation.
Combined magnetic and gravity data are interpreted to
indicate that the source is a basin-shaped body having a substantially
greater density than the adjacent rocks that lies at
a shallow depth. The lithology of the source is not known
because of a lack of subsurface data, but is inferred to be
either Precambrian iron-formation or mafic igneous rock.
The anomaly warrants further investigation. |
