Abstract:

The State Geologic Map Compilation (SGMC) geodatabase of the conterminous United States (https://doi.org/10.5066/F7WH2N65) represents a seamless, spatial database of 48 State geologic maps that range from 1:50,000 to 1:1,000,000 scale. A national digital geologic map database is essential in interpreting other datasets that support numerous types of national-scale studies and assessments, such as those that provide geochemistry, remote sensing, or geophysical data. The SGMC is a compilation of the individual U.S. Geological Survey releases of the Preliminary Integrated Geologic Map Databases for the United States. The SGMC geodatabase also contains updated data for seven States and seven entirely new State geologic maps that have been added since the preliminary databases were published. Numerous errors have been corrected and enhancements added to the preliminary datasets using thorough quality assurance/quality control procedures. The SGMC is not a truly integrated geologic map database because geologic units have not been reconciled across State boundaries. However, the geologic data contained in each State geologic map have been standardized to allow spatial analyses of lithology, age, and stratigraphy at a national scale. A full discussion of the procedures and methodology used to create this dataset is available in the accompanying report: Horton, J.D., San Juan, C.A., and Stoeser, D.B, 2017, The State Geologic Map Compilation (SGMC) geodatabase of the conterminous United States (ver. 1.1, August 2017): U.S. Geological Survey Data Series 1052, 46 p., https://doi.org/10.3133/ds1052.

Purpose:

The purposes of these data are to provide a standardized, vector-based, state geologic map database of the conterminous U.S. at an approximate scale of 1:1,000,000. The compilation includes new geologic information and state maps, corrections to the original Preliminary Integrated Geologic Map Databases for the United States (PIGMD), and enhancements which are explained in the accompanying report. The data are suitable for use in Geographic Information Systems (GIS) or other database and geospatial software used to derive maps and perform geospatial analyses. The information is intended to meet the needs of a wide community of users that extends from geosciences to State and Federal agencies, private industry, and the general public.

Supplemental_Information:

This SGMC Geodatabase (USGS_StateGeologicMapCompilation_ver1.1.gdb) contains 3 feature classes, 5 tables, and 4 relationship classes: SGMC_Geology – polygon feature class representing the state geologic units of the conterminous U.S. SGMC_Points – point feature class representing various geologic point features for some states. SGMC_Structure – polyline feature class representing linear geologic features (mostly faults) for some states. Units – table containing geologic unit information (province, name, description, age) for the state geologic units of the conterminous U.S. Age – table containing standardized geologic age information for the state geologic units. Lithology – table containing standardized lithologic information for the state geologic units. References – table containing all the references used to compile the data. Unit_Ref_Link – table of references used to link the tabular data to the geology feature class. Age_Relate – relationship class used to relate the Age table to the Geology feature class (one to one relationship – Key Field is UNIT_LINK). Lithology_Relate – relationship class used to relate the Lithology table to the Geology feature class (one to many relationship - Key Field is UNIT_LINK). Unit_Ref_Link_Relate – relationship class used to relate the Unit_Ref_Link table to the Geology feature class (one to many relationship - Key Field is UNIT_LINK). Units_Relate – relationship class used to relate the Units table to the Geology feature class (one to one relationship - Key Field is UNIT_LINK). Feature classes are also provided as Esri shapefiles. Note that attribute field names in the shapefiles are limited to 10-characters and entries are truncated to 254-characters. Geodatabase tables are also provided as CSV (comma-separated values) files.

Newly updated data for California (geology, structure and points).

Process_Step:

Process_Description:

The 48 separate databases forming the Preliminary Integrated Geologic Map Databases for the United States (PIGMD) were integrated into a single ArcGIS 10 file geodatabase. Outdated state maps were replaced with newer state geologic maps or geologic information where available. All data were compared to published state geologic maps to ensure spatial integrity and data were fitted to a USGS national-scale state boundary. Attributes in the original state geologic map databases were standardized to conform to the USGS SGMC format (see the accompanying data series report for details). Errors, primarily in the coding of attributes, were corrected when reported or encountered. Where appropriate, supporting tables were updated to reflect current USGS nomenclature and linkages between tables were checked.

Process_Description:

Version 1.1: California - replaced the original digital data (Saucedo, George J., Bedford, David R., Raines, Gary L., Miller, Robert J., and Wentworth, Carl M., GIS Data for the Geologic Map of California, California Geological Survey, CD 2000-07) with the newer version (Jennings, C.W., with modifications by Gutierrez, C., Bryant, W., Saucedo, G., and Wills, C., 2010, Geologic map of California, Version 2.0 (California Geological Survey 150th Anniversary Edition), Department of Conservation, California Geological Survey: California Geologic Data Map Series, GDM No. 2, scale 1:750,000.). The newer 2010 California data contains corrections of spatial errors of up to 1km in the older dataset and updated fault, and point features. See the original source metadata of California for more information.
