From August, 1977, to March, 1978, total field geomagnetic readings were taken at 948 sites in the following counties in North Dakota: Pembina County, Grand Forks County, and Walsh County east of 98°W. longitude. The field data was contoured by computer using the SYMAP commercial computer program. Nine major and several minor magnetic anomalies were discovered. Trends present on the aeromagnetic map of Minnesota continue westward into North Dakota. Limited bore hole data and the geomagnetic map suggest that the study area is underlain by Precatnbrian rocks of the Superior geologic province. The northernmost trend may indicate a western extension of the Vermilion fault.
