Description

Geologic interpretation of gravity and magnetic anomaly data in a given area is greatly enhanced if

density, magnetic susceptibility (MS) and natural remanent magnetization (NRM) data are available for

representative rock-types (Chandler and others, 2008). Along with geologic information from outcrop

and drill-holes, rock property data help relate geophysical anomaly signatures to probable rock types,

and provide constraints on the use of anomaly data as a tool for mapping and for modeling geology at

depth. Rock property data are particularly important to Minnesota where Precambrian rocks, which

comprise the bulk of the bedrock surface, are associated with a wide range of density, MS and NRM

values and are mostly under a thick cover of unconsolidated glacial sediments.
