This dataset portrays statewide total field aeromagnetic (airborne magnetic) data collected during1979-1991. The Minnesota Geological Survey developed this magnetic anomoly dataset which reflects variations in magnetization of underlying rocks from regional effects in units of nanoTesla. Certain rock types are commonly associated with their magnetic strength, and this dataset can aide in the identification of rock features on the landscape.
