Collection of Rock Properties from Minnesota The current database consists of location 9,032 entries. The surface-based, point data include 5,272, 6,939, and 903 density, magnetic susceptibility, and NRM measurements, respectively. Downhole data from 146 drillcore have also been incorporated, yielding an additional 1,145 and 9,622 measurements of density and magnetic susceptibility, respectively. 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...

Within target cells, each a quarter-degree latitude by a half-degree longitude, till from between about 1 and 2 m depth was sampled by filling a 15 liter plastic pail. At a few sites, vertical profiles were collected. In addition, three transects to the north were sampled, to help identify sediments derived by long-distance glacial transport, to obtain reference samples from the Thompson nickel belt, and also to extend sampling to the limit of Hudson Bay-derived carbonate-bearing sediments, to permit comparison to Minnesota...
