Description: 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.

Copyright Text: The State Geologic Map Compilation of the Conterminous United States was developed by the U.S. Geological Survey Mineral Resources Program (MRP). The project owes its success to numerous MRP staff who compiled the Preliminary Integrated Geologic Map Databases for the United States (PIGMD) as well as the foundational geologic mapping work completed by U.S. State Geologic Surveys and academia.
Description: This feature class was created from a multitude of map and published references. Many of the maps were scanned, digitized, and georeferenced to the map document with projection NAD 1983 UTM Zone 14N. Minor modifications were made to ensure continuity with other published data.The excel table 'attributetable2' includes the intended attributes for most structures.

Ispoachs are thickness contours measured in feet (ft) and defined as the difference between the top of the producing formation and the next distinct formation top of a deeper formation. Data as of April 2020.

Description: The Wolfcamp D formation is part of the Wolfcamp play which is a mixed shale and argillaceous carbonate play in the Midland Sub-basin of the Permian Basin. Elevation contours are measured in feet (ft) and defined as true vertical depth to producing formation top and calculated by subtracting true vertical drilling depth from the elevation reference measured at the drilling site. Data as of April 2020.
