Abstract:

This digital map portrays the bedrock geology of the states of Michigan, Wisconsin, and Minnesota taken from the most recent published regional compilations. Some minor modifications and generalizations have been made from the published maps. Information on mineral deposits of the three states is from the U.S. Geological Survey's Mineral Resource Data System (MRDS).
Version 3.0 supercedes the original report released in 1997. It differs from the original map in having expanded attribute information assigned to geologic units and updated shoreline and state boundaries. The new attributes allow expanded capabilities for producing derivative maps for attributes including stratigraphy, lithology, and tectonic settings. The new shoreline and state bounaries offer greater geographic accuracy than the originally published version.

Purpose:

This product is intended to provide a regional overview of mineral deposits and their relation to regional geology and is not intended for use at scales greater than 1:500,000.

Horizontal_Positional_Accuracy_Report:

Various users have had differing requirements for locational precision of deposit sites. The result is that some original records give only approximate locations. We have reviewed the locations for the deposits contained in the included files with the aim of having all deposit locations correct to within 2 seconds of latitude and longitude.
