"A vertical intensity magnetic survey of 144 square miles in Christian County, southwest Missouri revealed an 825 gamma anomaly having a closure of 9 square miles. A three mile gravity traverse across the magnetic anomaly detected a positive gravity anomaly in excess of six mllligals.
Calculations showed that a Precambrian hill large enough to cause the observed magnetic anomaly would outcrop at the surface. Because Precambrian rocks are known to be buried under a sedimentary layer, this hypothesis was rejected.
Theoretical anomalies of several geometrical bodies at calculated depths were visually compared with the measured magnetic and gravity profiles. A …
