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. Following a regional meeting of the State compilers with the coordinator to establish map units and related matters, separate Quaternary maps and map explanations of the part of each State included in the quadrangle were prepared by the State compilers. These maps and explanations were then assembled and integrated and supplemented by the editors to produce the quadrangle map and map explanation. Problems related to differentiation and description of saprolite units, and to definition of map units for the Quaternary deposits of the Coastal Plain, were resolved at additional meetings as well as by correspondence. The footnote on saprolite was prepared by E. T. Cleaves, Maryland Geological Survey, and R. B. Daniels, North Carolina State University. The tentative correlation of Quaternary and upper Pliocene stratigraphic units was prepared by G. M. Richmond with the cooperation of D. C. Colquhoun, W. H. Wheeler, G. H. Johnson, and J. P. Owens. Agreement among workers was not unanimous, in part due to difficulties of dating materials. The other diagrams and charts were prepared by the editors. The compilers reviewed the map prior to its submittal for publication. NOTE 2: The Pliocene-Pleistocene boundary defined by joint resolution of the International Union for Quaternary Research (INQUA) Subcommission l-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 (Neogene/Quaternary Boundary) is that 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).

Browse_Graphic_File_Type: PDF Data_Set_Credit: The Quaternary Geologic Map of the Savannah 4° x 6° Quadrangle, United States, I-1420 (NI-17) was compiled by: Michael S. Friddell and Amy K. Van Nostrand, Georgia Geological Survey; Donald J. Colquhoun, University of South Carolina; Walter H. Wheeler and Joel P. Gregory, University of North Carolina; Raymond B. Daniels, North Carolina State University; and Robert A. Miller, Tennessee Division of Geology. The State compilations were edited and integrated by Gerald M. Richmond, David S. Fullerton, and David L. Weide, U.S. Geological Survey. The compilations of geology, topography, and hydrology were converted to digital form by TechniGraphic Systems, Inc., of Fort Collins, Colo., under contract with the U.S. Geological Survey and modified by Charles A. Bush. The illustrations, word-processor files, and National Atlas coverages were prepared by Bush. Native_Data_Set_Environment: Windows_XP, 4.0, Intel ArcInfo version 9.1 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 green-line material and published paper map, vectorized scan, attributed files, and produced check plots and coverages. C.A. Bush 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 marine scarps. 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.

Due to significant differences between the greenline and the paper map, water boundaries were resolved using the paper map. Process_Date: 2001 Process_Step: Process_Description: Coverages 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 (Bush). 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 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. Process_Date: 2008 Process_Step: Process_Description: C.A. Bush created illustration of the index map on the paper map in a drawing program and changed it to reflect the status of conversion of Quaternary Geologic Atlas quadrangles to digital databases. Bush scanned original printed map and also separated State compilation responsibility and map unit correlation diagrams, cleaned the scans, and converted them to PDF format. Process_Date: 2008 Process_Step: Process_Description: Map unit descriptions and sources of information as given on the printed map were scanned and converted by an Optical Character Recognition computer program into text files and to PDF format(Bush). Process_Date: 2008 Process_Step: Process_Description: Illustrations and text files were checked and edited by Bush.
