Description:
Abstract:
This data set contains boundaries and tags for major geologic units in the
conterminous United States. In addition to the polygons representing the
areal extent of geologic units, it identifies boundaries of metamorphic
provinces, major faults, calderas, impact structures, and generalized
limits of continental glaciation. The data depict the geology of the
bedrock that lies at or near the land surface, but not the distribution of
surficial materials such as soils, alluvium, and glacial deposits. This
is a revised version of the April 2004 data set. This map complements the
Generalized Geologic Map of Alaska, Hawaii, Puerto Rico, and the U.S.
Virgin Islands by Reed and Bush.
The data are generalized from a compilation prepared for use in the
Geologic Map of North America, to be published in hard copy by the
Geological Society of America and released as a digital file by the U.S.
Geological Survey.
Purpose:
These data have been prepared with a degree of detail appropriate for
viewing at a scale of 1:7,500,000. Because of the degree of
generalization required (generalization based on compilation scale), the
data are intended primarily for display and for regional and national
analysis, rather than for more detailed analysis in specific areas.
No responsibility is assumed by the U.S. Geological Survey in the use of
these data.
Supplemental_Information:
The data set for the Geologic Map of the Conterminous United States
consists of nine data layers. The data layers for faults and glacial
limit lines are included in two different versions. The data are
available as shapefiles, ArcInfo Export files, or graphics files
(includes PDF, EPS, and AI formats). The data layers are distributed and
should be used together. All the data layers were created as ARCINFO
coverages and converted to other formats for distribution purposes. The
following files are included:
> Calderl075 - Outlines of major calderas and impact structures
> Faultgl075 - Fault lines, with line decorations*
> Faultl075 - Fault lines, without line decorations**
> Geolgym075 - Geologic units, as polygons
> Geotxtl075 - Graphic representation of geologic unit text*
> Glacagl075 – Generalized glacial limit lines, with line decorations*
> Glacall075 – Generalized glacial limit lines, without line decorations**
> Impactx075 - Impact structure locations, as points
> Metfacp075 - Areas and facies types of metamorphism, as polygons
>
>* these files are not 'true' ArcInfo coverages; they are graphic
> representations of symbols and text used on the geologic map. These
> files should be used to produce appropriately symbolized graphics.
> The decorations and text only appear correctly in Lambert Azimuthal
> Equal Area projection. The parameters for the projection are:
> Projection Lambert Azimuthal Equal Area
> Datum NAD83
> Spheroid GRS1980
> Units Meters
> Radius of the sphere of reference 6370997
> Longitude of center projection -100
> Latitude of center of projection 45
>
>** these files are the same as the files marked with * but do not
> include the line decorations. They are the 'true' fault and glacial
> limit line ArcInfo coverages. These files should be used for data
> analysis.
Also distributed with the data is the shadeset, geoshade.shd.
Any use of trade, product, or firm names is for descriptive purposes only
and does not imply endorsement by the U.S. Government
Although this Federal Geographic Data Committee-compliant metadata
file is intended to document the data set in nonproprietary form, some
ArcInfo-specific terminology is included for clarity and expediency.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The line attributes were manually checked by assigning unique line
types to the values and then plotting the data. The plots were
then compared to the source.
The polygon attributes were checked by visually comparing the final
colored plots to maps at various larger scales.
Logical_Consistency_Report:
Polygon and node topology are present. All polygons are labeled and were
tested by using the ArcInfo command LABELERRORS. All polygons were checked
for closure, node errors, overshoots, undershoots, dangles and intersections
using ArcInfo routines. The ArcInfo commands BUILD and CLEAN were run to
ensure the topological consistency of the data set.
Completeness_Report:
This data set contains map unit boundaries and codes for the 48
conterminous States. Boundaries and codes are included for geologic
units, metamorphic facies, limits of glacial advance, impact structures,
caldera boundaries, and major faults.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The accuracy of the original data was checked by comparing the digital
files to several data sources. Both the line work and the polygon
labels were checked against the source compilation.

Process_Description:
The geologic unit polygons (geolgym075), faults (faultl075), generalized
glacial limit lines (glacall075), boundaries of metamorphic provinces
(metfacp075), calderas (calderl075), and impact structures (impactx075)
were created using the following procedures:
Data were compiled on scale-stable clear film at various scales. The
lines and points were then digitized and georeferenced using the
computer program GSMCAD, written by Van S. Williams, USGS. The program
is available at no charge at
. Polygons, lines, and
point features were attributed in GSMCAD.

Supplementary graphical coverages were created for the faults
(faultgl075) and generalized glacial limit lines (glacagl075). These
are the same as faultl075 and glacall075 except decoration lines have
been added for display purposes. Another coverage was created
containing arcs that represent text labels for the polygons
(geotxtl075). This is also for display purposes.

Geologic unit (described by geolgym075.pat or geolgyp.dbf)
Entity_Type_Definition:
Rock and material that lies at or near the land surface, but not
surficial materials such as soils, alluvium, and glacial deposits. The
units are defined by sedimentary, volcanic, plutonic, or metamorphic
rock types and by their geologic age. The Text attribute is included to
provide a method for generating the appropriate map symbols for display
and publication purposes.

not have the special symbols used for geologic time periods, the symbols
were created in GSMCAD and exported as arcs.
