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 1: This map is the product of interorganizational collaboration. Map units and related matters were established in general at a regional meeting of state compilers with the coordinator. Subsequently, Quaternary maps and map explanations of the part of each state included in the quadrangle were prepared by the state compilers. These were then integrated and supplemented by the editors to produce this geologic map and map explanation. Significant geologic problems were resolved by correspondence. The map was reviewed by the compilers prior to being submitted for publication. Other reviewers, to whom the editors are indebted, were W. A. White, Department of Geology, University of North Carolina, and J. B. Cathcart, U.S. Geological Survey. NOTE 2: The Pliocene-Pleistocene boundary as defined by joint resolution of the International Union for Quaternary Research (INQUA) Subcommission 1–d on the Pliocene/Pleistocene Boundary, the International Commission on Stratigraphy (ICS) Working Group on the Pliocene/Pleistocene Boundary, and the Working Group of the International Geological Correlation Program (IGCP) Project No. 41 on the (Neogene/Quaternary Boundary) is at the Vrica section in southern Italy. The age of that boundary currently is inferred to be 1.65 Ma (Aguirre and Pasini, 1984). Time boundaries between the early Pleistocene and middle Pleistocene and between the middle Pleistocene and late Pleistocene are being proposed by the INQUA Working Group on Major Subdivision of the Pleistocene. The boundary between the early Pleistocene and middle Pleistocene is placed at the Matuyama-Brunhes magnetic polarity reversal. The reversal has not been dated directly by radiometric controls. It is significantly older than the Bishop Tuff (revised K-Ar age 738 ka; Izett, 1982), and the estimated K-Ar age of 730 ka assigned to the reversal by Mankinen and Dalrymple (1979) is too young. In Utah, the Bishop volcanic ash bed overlies a major paleosol developed in sediments that record the Matuyama-Brunhes reversal (Eardley and others, 1973). The terrestrial geologic record is compatible with the astronomical age of 788 ka assigned to the reversal by Johnson (1982). The boundary between the middle Pleistocene and late Pleistocene is placed arbitrarily at the beginning of marine oxygen isotope substage 5e (at Termination II or the stage 6/5 transition). That boundary also is not dated directly. It was assigned provisional ages of 127 ka by CLIMAP Project members (CLIMAP Project Members, 1984) and 128 ka by SPECMAP Project Members (Ruddiman and McIntyre, 1984), based on uranium-series ages of the substage 5e high eustatic sea level stand.A sidereal age of 132 ka is derived by projection of the boundary onto the astronomical time scale of Johnson (1982). The Pleistocene-Holocene boundary is being proposed by the INQUA Subcommission on the Holocene. Currently in the United States, it is placed arbitrarily at 10,000 B.P. (Hopkins, 1975).

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, linear features, 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; location and age of ancestral deltas of the Mississippi River; and showing 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. >The dataset for the Jacksonville quadrangle consists of 10 coverages. > geo_net > geo_poly > geo_lin > hydr_lin > topo_lin > bnd_lin > bnd_poly > rd_lin > rr_lin > grid_lin > The dataset also includes an ArcInfo AML and shadeset that will produce the Illustrator or ArcInfo PDF file of the geology and list of map units.

Browse_Graphic_File_Type: PDF Data_Set_Credit: The Quaternary Geologic Map of the Jacksonville 4° x 6° Quadrangle, United States, I-1420 (NH-17) was compiled by: Thomas M. Scott and Michael S. Knapp, Florida Bureau of Geology; Michael S. Friddell, Georgia Geologic Survey; David L. Weide, U.S. Geological Survey. The map was edited and integrated by Gerald M. Richmond, David S. Fullerton, and David L. Weide, U.S. Geological Survey. The compilation of geology, hydrology, and topography was converted to digital form by TechniGraphic Systems, Inc., of Fort Collins, CO, under contract with the U.S. Geological Survey and modified by Charles A. Bush. Native_Data_Set_Environment: Windows_XP, 4.0, Intel ArcInfo version 9.2 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 that 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, topographic lines, and water boundaries, vectorized scan, attributed files, and produced check plots and coverages of map units. The contractor also scanned and converted hydrography and topography from the stable-base mylar. 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. 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. Lineage: Source_Information: Source_Citation: Citation_Information: Originator: Gerald M.

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: 2009 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 was 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.
