Description:

Abstract:

These digital maps are a reformulation of previously published maps, primarily maps of states. The reformulation gives all the maps the same structure and format, allowing them to be combined into regional maps. The associated data tables have information about age and lithology of the map units, also in a standard format.

Purpose:

Provide digital maps and databases that, because of their common structure and format, allow creation of regional maps that depict age and lithology of map units.

Supplemental_Information:

The data is provided in decimal degrees and in Lambert Conformal Conic projection. The data is provided in both coverage and shapefile format, and includes supplemental attribute tables. No attempt was made to reconcile differences in mapping across state boundaries.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Map unit designations follow original compilation faithfully. Additional information about age and lithology was obtained from the paper map legend and geologic literature.

Logical_Consistency_Report:

All internal polygons were checked for closure. Overshoots and undershoots have been deleted or corrected as appropriate.

Completeness_Report:

The dataset contains all the map units and faults that were portrayed on the original printed map. Bodies of water are classified as water, and geologic units underlying them are not portrayed.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The geologic map was digitized from compilations ranging in scale from 1:100,000 to 1:1,000,000, and is an accurate representation of the source maps. It is intended to be used at scales equal to or smaller than 1:500,000. Display at significantly larger scales may produce error in location of contacts or faults relative to features contained in other data sets. The state boundary arcs are based on the 1:100,000 scale USGS topographic map series digital line graphs.

Process_Step:

Process_Description: Dataset copied.
Process_Date: 2003

Process_Step:

Process_Description:

Adjusted the perimeter of the coverage to match a reference dataset of state boundaries derived from 1:100,000 scale digital line graphs. This allows the map to be used together with adjoining state maps referenced to the same boundary data. Replaced a section of the state boundary that follows the Colorado River with a line from 1:100,000 scale digital line graph hydrographic files. The state boundaries have a source of US001 in the AAT.

Process_Date: 2004

Process_Step:

Process_Description:

Thirty-one arcs had their polarity flipped to conform to the right-hand rule (source in AAT = NV801)

Process_Date: 2004

Process_Step:

Process_Description:

One arc was assigned ARC-CODE = 4, to conform to the printed map (source in AAT = NV802)

Process_Date: 2004

Process_Step:

Process_Description:

Changed map unit to Ta3, and eliminated one polygon (SP_OBJ_ID=32012272), after Whitebread, D.H. and John D.A., 1992, USGS MF-1877-A (source in PAT = NV901)

Process_Date: 2004

Process_Step:

Process_Description:

Completed a dangling arc to create new polygon, to conform to printed map (source in PAT = NV902)

Process_Date: 2004

Process_Step:

Process_Description:

Updated the map unit label for 229 plutonic rock polygons, using age information developed in 1989, during preparation of the Nevada Mineral Resource Assessment (Nevada Bureau of Mines and Geology Open-File report OF96-2) (source in PAT = NV903)

Process_Date: 2004

Process_Step:

Process_Description:

Updated the map unit label for 33 plutonic rock polygons, using literature information, personal communications, and the National Radiometric Age Database (source in PAT = NV904)

Process_Date: 2004

Process_Step:

Process_Description:

To prepare a uniform AAT file, the following items were added: arc-code, arc-para1, and arc-para2. The last two are not used. Arc-code was populated, using the information in the original item, and inspection of the printed map. Then the original items in the AAT were deleted (LINECODE, FAULT_CONT, DWNTHR, SOURCE_ID, SPATIAL_OBJ_ID)

Process_Date: 2005

Process_Step:

Process_Description:

To prepare a uniform PAT file, the following items were added: ORIG_LABEL, SGMC_LABEL, UNIT_LINK, SOURCE, UNIT_AGE, ROCKTYPE1, and ROCKTYPE2. ORIG_LABEL was populated from the original item (PTYPE), SGMC_LABEL and UNIT_LINK were populated with information in the accompanying attribute table AZunits, UNIT_AGE was populated with information in the accompanying attribute table AZage, and ROCKTYPE1 and ROCKTYPE2 were populated with information in the accompanying attribute table AZlith. Then the original items in the PAT were deleted (MAP_UNIT, UNIT, SOURCE_ID, SPATIAL_OBJ_ID)
