    Geologic Map Mesabi Iron Range, Minnesota, second edition
    (Mesabi Range Geological Society (MRGS) and Minnesota Geological Survey, 1999) Meineke, David G; Buchheit, Richard L; Dahlberg, Henk E; Morey, G B; Warren, LeRoy E
    Historic strip-map of a 100 mile-long, 10 mile-wide area covering portions of St. Louis and Itasca counties, and enclosing the Mesabi Iron Range and parts of the Duluth Complex. Scale 1: 62500. First compiled and released in 1993, this map has never been formally published with a cite-able reference. Data and assistance for the compilation was provided by numerous companies, individuals and organizations which are listed on the map plate. The map has been in the charge of the Mesabi Range Geological Society and they have provided the MGS permission to host a scanned version of this map under the MGS holdings on the University of Minnesota Digital Conservancy (2019). The original map of 1993 has been superseded by the 1999 edition to correct certain errors in the cartographic base. The geology portion of the map was not altered.

    Minnesota at a Glance Water in Minnesota
    (Minnesota Geological Survey, 2017) Dengler, E.L.
    Water is arguably the most important resource on our planet. All life depends on it for survival. Approximately 71% of the surface of the Earth is water and of this, about 97% is saltwater. Where fresh water is present largely depends on geology, geographic location, global weather processes, and topographic variability.

    Upgrade of the Gravity Database
    (2011) Chandler, V.W.; Lively, R.S.
    The principal fact gravity database in Minnesota is comprised of over 59,000 measurements collected since 1950. It contains point location data, elevations, free-air and Bouguer anomaly values, field information and base U.S.G.S. quadrangle locations. Over the years gravity data in Minnesota has proven to be a useful resource for the Minnesota Geological Survey (MGS) in its mission of bedrock mapping, and it has provided mineral exploration companies with a significant supplement to exploration programs in Minnesota. Because much of the Precambrian bedrock in Minnesota lies beneath thick glacial deposits, gravity measurements, which are sensitive to density variations, are particularly helpful at inferring structures and rock types deep in the subsurface. The state-wide gravity data is most commonly used in conjunction with the high- resolution aeromagnetic data from Minnesota, which is highly sensitive to magnetic variations in the underlying Precambrian rocks.In 2003, the MGS released a state-wide gravity database with 57890 stations (gravity meter readings). This is an update to that database.

    Bedrock geology of Minnesota: Postcard
    (Minnesota Geological Survey, 1996) Tipping, R.G.; Lusardi, B.A.
    This simplified geologic map shows the general distribution of rock types underlying Minnesota's landscape. Some of the rocks are 3.6 billion years old-the oldest found so far in the United States.

    Quaternary geology of Minnesota: Postcard
    (Minnesota Geological Survey, 1996) Lusardi, B.A.
    This simplified geologic map shows the general distribution of surficial sediments in Minnesota. During the Pleistocene Epoch (2 million- 10.000 years ago J. glaciers advanced into Minnesota several times from different directions-the Superior lobe from the northeast; the Rainy lobe from the north-northeast; the Wadena lobe from the north; and the Des Moines lobe from the northwest.

    Bedrock geology of Minnesota: Postcard
    (Minnesota Geological Survey, 1992) Morey, G.B.
    This interim geologic map shows the general distribution of rock types underlying Minnesota's landscape. Some of the rocks are 3.6 billion years old - the oldlest found so far in the United States. The map reflects geologic ideas developed by scientists during the past decade. Because the map was compiled from large-scale maps, large parts of which were interpreted from geophysical data, this image should not be photographically or digitally enlarged for use at a more detailed scale.
