Abstract:
The Quaternary Geologic Map of the Vicksburg 4° x 6° Quadrangle
was mapped as part of the Quaternary Geologic Atlas of the United States.
The atlas was begun as an effort to depict the areal distribution of
surficial geologic deposits and other materials that accumulated or
formed during the past 2+ million years, the period that includes all
activities of the human species. These materials are at the surface of
the Earth. They make up the "ground" on which we walk, the "dirt" in
which we dig foundations, and the "soil" in which we grow crops. Most
of our human activity is related in one way or another to these surface
materials that are referred to collectively by many geologists as
regolith, the mantle of fragmental and generally unconsolidated material
that overlies the bedrock foundation of the continent. The maps were
compiled at 1:1,000,000 scale.
Purpose:
In recent years, surficial deposits and materials have become the
focus of much interest by scientists, environmentalists, governmental
agencies, and the general public. They are the foundations of
ecosystems, the materials that support plant growth and animal
habitat, and the materials through which travels much of the water
required for our agriculture, our industry, and our general well
being. They also are materials that easily can become contaminated
by pesticides, fertilizers, and toxic wastes. In this context, the
value of the surficial geologic map is evident.
NOTE: This map is the product of collaboration of State geological surveys,
universities, and the U.S. Geological Survey, and is designed for both
scientific and practical purposes. It was prepared in two stages. First,
separate maps and map explanations of the parts of States included in the
quadrangle were prepared by the State compilers indicated on the inset
diagram, Areas of Responsibility. Second, these maps were combined,
integrated, locally supplemented, and related to a uniform map symbol
classification. The map unit descriptions also were combined, supplemented,
and coordinated with those of other maps of this series so that individual
unit descriptions are applicable throughout both this map and all other maps
of the series. Diagrams accompanying the map were prepared by the editors.
Differences in mapping or interpretation in different areas were resolved by
correspondence to the extent possible. Most simply reflect differences in
available information or differences in philosophies of mapping. Such
differences serve to encourage further investigation.
Less than forty percent of the surficial deposits of the United States have
been mapped and described. Traditionally, mapping of surficial deposits has
been focused on glacial, alluvial, eolian, lacustrine, marine, and landslide
deposits. Slope and upland deposits have been mapped in detail only in
restricted areas. However, an enormous amount of engineering construction
and many important problems of land use and land management are associated
with regions that have extensive slope and upland deposits (colluvium,
residuum, and saprolite, for example). These materials have many different
physical characteristics. Therefore, an effort has been made to classify,
map, and describe there deposits, based in large part on unpublished
interpretations of individuals, published and unpublished subsoil data, and
the distribution of bedrock parent materials. The classification is crude,
but represents a first step toward a more refined and useful product.
For scientific purposes, the map differentiates Quaternary surficial
deposits on the basis of a combination of criteria, such as lithology,
texture, genesis, stratigraphic relationships, and age, as shown on the
correlation diagram and indicated in the map unit descriptions. Some
geomorphic features, such as sand dunes, are distinguished as map units.
Erosional features, such as stream terraces, are not distinguished, and
differentiation of sequences of alluvial deposits of different ages is rarely
possible at a scale of 1:1,000,000. Most landslide deposits also are too
small to be shown at this scale.
For practical purposes, the map is a surficial materials map, on which
materials are distinguished on the basis of texture, composition, and
local specific characteristics such as swelling clay. It is not a map of
soils as soils are recognized and classified in pedology or agronomy.
Rather it is a generalized map of soils as recognized in engineering geology,
or of subsoils or parent materials from which pedologic and agronomic soils
are formed. As a materials map it serves as a base from which a wide variety
of derivative maps for use in planning engineering, land use, or land
management projects can be compiled.
Supplemental_Information:
This database represents an attempt to digitally capture all
the geologic information available on the published paper map.
Separate coverages are provided for the map unit polygons
and line coverages for the hydrology and topography.
The description of map units and sources of information are
both included as a PDF file.
The published maps of the Quaternary Geologic Atlas of the United
States used three separate projections. To promote uniformity, the
projection of this database was changed from Lambert Conformal Conic to
Albers Equal Area and all subsequent digital databases will similarly
be changed to Albers Equal Area Projection.
Illustrations are provided showing an index to the International Map
of the World 1:1,000,000; areas of responsibility for the compilation
of the map; distribution and thickness of loess in the map area;
and show the correlation of map units.
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, as
well as in ArcInfo format, this metadata file includes some
ArcInfo-specific terminology.

Data_Set_Credit:
The Quaternary Geologic Map of the Vicksburg 4° x 6° Quadrangle,
United States, I-1420 (NI-15) was compiled by: Drew F. Holbrook and
William V. Bush, Arkansas Geological Commission; William A. Gilliland,
Mississippi Geological Survey; Kenneth V. Luza, Kathryn N. Jensen, and
William D. Fishman, Oklahoma Geological Survey; David E. Pope, Louisiana
Geological Survey; E. Gerald Wermund, Texas Bureau of Economic Geology;
and Robert A. Miller, Tennessee Division of Geology.
The compilation of geology was converted to digital form by Techni Graphic
Systems, Inc., of Fort Collins, CO, under contract with the U.S. Geological
Survey and modified by Charles A. Bush. The topographic and hydrographic
coverages, illustrations, word-processor files, and National Atlas coverages
were prepared by Bush.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Compilation of geologic data:
The accuracy of the map data is dependent on (1) the accuracy of the
original source data, (2) the accuracy of transfer of those data to
larger scale bases by the compilers, (3) the procedures by which the
compilers and the editor/integrator simplified or generalized the data,
and (4) the procedures used by, and the objectivity exercised by, the
editor/integrator in integration of adjacent parts of the map that were
prepared by different compilers. Consequently, aspects of accuracy for
the data set cannot be quantified.
Digitization and attributing of compilation:
Digitizing contractor scanned source stable-base contact lines and
water boundaries from the published paper map, vectorized scan, attributed
files, and produced check plots and coverages of map units. Bush digitized
hydrography and topography from the published paper map. C.A. Bush
rectified differences between the geology and the hydrology, proofread
check plots, added additional attribution, and reviewed digital files;
made final corrections as needed; produced graphical files and imported
them into graphics program to prepare plot file; proofread cartographic
product; prepared illustrations and word-processing files of descriptions
of map units and sources of information. The original paper map was
scanned and recreated as PDF files. (The original map was thoroughly
reviewed for conformity with U.S. Geological Survey editorial standards
and stratigraphic nomenclature.)
Logical_Consistency_Report:
Polygon and chain-node topology are present. The ArcInfo commands BUILD
and CLEAN were run to ensure the topological consistency of the data set.
All polygons are labeled and were tested by using the ArcInfo command
LABELERRORS. All polygons were checked for closure and intersections.
Completeness_Report:
These coverages contain polygons for all the map units, and lines for all
the contacts and shorelines. All geologic data from the original map are
expressed on this map. Any differences between elements on the original
map and attributed polygons or arcs in this database are inadvertent and
should not be construed as deliberate alterations of the data except the
addition of unit "slc."
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The accuracy of location of polygons, lines, and points is consistent
with the map scale of 1:1,000,000. The digital file was prepared at
1:1,000,000 nominal viewing scale. If the map is enlarged to larger
scales (for example, 1:250,000, 1:100,000, or 1:24,000 scale), resolution
of the map data is greatly diminished. Enlargement will not restore
resolution that was lost by simplification or generalization
of data.

and attributed files and produced check plots and coverages.
Process_Date: 1992
Process_Step:
Process_Description:
C.A. Bush scanned paper map, vectorized hydrology and topography and
converted into ArcInfo coverages. Water boundaries were resolved
using the paper map. Coverage of geology was checked and corrected
or changed. Additional items were included in the attributes. AML's
were created to plot the data. Plots were imported into graphics
program to create a plotfile of the digital map.
Process_Date: 2008
Process_Step:
Process_Description:
Bush acquired National Atlas of the United States 1:2,000,000 digital
data for roads, railroads, and county boundaries in the United States.
Data were clipped to cover only the area of the map. Since the files
are intended only for the user's reference, and to reduce file size,
all attributes were removed from the railroad coverage. All
attributes were removed from the roads coverage except U.S. and
State highway designations. A coverage was created containing
map boundaries, and State and county boundaries. These coverages
do not exactly match the base used in preparation of the original
Quaternary Atlas map, but are included for the user's convenience.
