Spatial data supporting the Basement tectonic framework of the U.S. Project were developed by the U.S. Geological Survey Mineral Resources Program (MRP).
This map of basement domains of the conterminous U.S. and Alaska is intended for use as a base layer for national-scale mineral resource assessments. The compositions, architecture, and original metals endowments are potentially important to assessments of primary mineral deposits and to the residence and recycling of metals in the crust of the U.S. parts of the North American continent. The database can be used to demonstrate the construction of the U.S. through time, to identify specific types of crust, and to identify domains potentially containing metal endowments of specific genetic types or endowed with specific metals.
