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...

The notes include basic data used to compile annual reports and bulletins on geological matters. For a description of the extent of geological work performed during the eras of the MGNHS and MGS, consult George M. Schwartz, “History of the Minnesota Geological Survey,” which identifies the individual studies made by officers of the survey between 1872 and 1963. The MGS was a major source of funding for faculty research, which focused on field petrology, mineralogy and economic geology and aligned to the individual professional...
