Seventy-seven basement domains are represented as eighty-three polygons on the map. The domains are based on interpretations of basement composition, origin, and architecture and developed from a variety of sources. Analysis of previously published basement, lithotectonic, and terrane maps as well as models of planetary development were used to formulate the concept of basement and the methodology of defining domains that spanned the ages of Archean to the present but formed through different processes. The preliminary compilations for the study areas utilized these maps, national-scale gravity and aeromagnetic data, published and limited new age and isotopic data, limited new field investigations, and conventional geologic maps. Citation of the relevant source data for compilations and the source and types of original interpretation, as derived from different types of data, are provided in supporting descriptive text and tables. The tectonic settings for crustal types represented in the basement domains are subdivided into constituent geologic environments and the types of primary metals endowments and deposits in them are documented. 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 United States portion of the North American continent. The databases can be configured to demonstrate the construction of the United States through time, to identify specific types of crust, or to identify domains potentially containing metal endowments of specific genetic types or endowed with specific metals. The databases can also be configured to illustrate other purposes chosen by users. Purpose: 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. Supplemental_Information: Datasets in this geospatial database include "Bsmnt_CONUS_AK", the polygon feature class of basement domains, and "tbl2_Environs_Deposits", tabular data for additional geologic and deposit information. The tabular data can be joined to the polygon features using the field “Crust_Type”. The “Reference” field in both layers lists abbreviated citations; complete bibliographic citations are provided in the accompanying report, as well as a general overview of the work performed by study area. Please note: attribute field names are truncated to 10-characters in the “shapefile” version of the geodatabase.

Values within descriptive fields represent new terminology developed by the report authors (for example, Crust_Type), or are modified from published geologic maps and reports (for example, Crust_Formation_Age) and therefore dependent on the accuracy of the source. Logical_Consistency_Report: Polygons in this dataset were checked for topological consistency (polygonal gaps and overlaps were corrected). Attribute fields containing dates were visually inspected for logical consistency (e.g. the age of crustal formation was greater than the age of crustal accretion). Completeness_Report: Dataset coverage includes the continental U.S. and Alaska. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The positional accuracy of basement domain boundaries is dependent on the source, scale, and accuracy of the base materials. In general, positional accuracy is approximate, highly variable, and not accurate at scales larger than 1:5,000,000.
