These data include all geologic information that: (1) has been collected, and (2) can be represented on a map within the map borders at the map scale is included in the map digital coverages. Purpose: These data were collected in support of the Department of Energy (DOE) activities at the NTS. The data were collected to provide both detailed information and a regional synthesis of geologic knowledge of the NTS. Supplemental_Information: The following coverages are included with this dataset: >Coverage Type Description >------------------------------------------ >geolpoly Polygon Geologic outcrops >geolflts line Fault traces >geolatts Point Bedding attitudes, etc. >geolcald line Caldera boundaries >geollins line Interpreted lineaments >geolmeta line Metamorphic gradients These coverages are attributed with numeric values and interpreted information. The entity files documented below show the data associated with each coverage. /* Procedures_Used The original digital data came from the SCITEX scan used to print the first NTS geologic map. More detailed information was compiled from unpublished digital geologic data at a scale of 1:24,000 and generalized for presentation at 1:100,000. Digital data was compiled from aerial photography annotated with field geologic data. Further data was supplied from unpublished geologic map information in many forms. /* Revisions This is Revision 3 of this data set. See references for previous revisions. /* Reviews_Applied_to_Data: The geologic data content has been reviewed by geologists of the National Cooperative Geologic Mapping Program and the data structures by GIS specialists also of the National Cooperative Geologic Mapping Program. /* Related_Spatial_and_Tabular_Data_Sets: The following coverages are related to the main database and are included with the database.
