README for Indiana Geological and Water Survey Quaternary Geology of the Indiana Portion of the Eastern Extent of the South Bend 30- x 60-Minute Quadrangle TITLE: Quaternary Geology of the Indiana Portion of the Eastern Extent of the South Bend 30- x 60-Minute Quadrangle By José Luis Antinao, Robin F. Rupp, and Matthew R. Johnson ABSTRACT: The Quaternary Geology of the Indiana Portion of the Eastern Extent of the South Bend 30- x 60-Minute Quadrangle is an Esri File Geodatabase that contains eight feature data sets and five geodatabase tables detailing the Quaternary geology of the Eastern Extent of the South Bend 30- x 60-minute quadrangle in Indiana. This data set conforms to "GeMS (Geologic Map Schema)--a standard format for the digital publication of geologic maps." For more information on GeMS, please refer to the supplemental information within this metadata. The ContactsAndFaults layer shows the geologic contacts within the map area. PURPOSE: The Quaternary Geology of the Indiana Portion of the Eastern Extent of the South Bend 30- x 60-Minute Quadrangle was created to provide digital access to the Quaternary geology of the eastern extent of the South Bend 30- x 60-minute quadrangle in Indiana. This geodatabase presents basic Quaternary geological information that contributes to the development of a three-dimensional framework of the state of Indiana. The data are synthesized from archived public domain geological data obtained from many different sources, original data obtained from fieldwork conducted by the authors, and contract drilling supported by project funds. Archive data sources include water-well records, refraction seismic surveys, borehole descriptions and geophysical logs, and the geological literature. Project data includes observations and measurements from drilled and sampled boreholes and estimated bedrock depths from analysis of horizontal-vertical spectral ratios (HVSR) seismic measurements. This database is, in large part, the result of a cooperative mapping agreement between the U.S. Geological Survey (USGS) and the Indiana Geological and Water Survey through the STATEMAP program of the USGS. SUPPLEMENTARY INFORMATION: The Quaternary Geology of the Indiana Portion of the Eastern Extent of the South Bend 30- x 60-Minute Quadrangle is a composite geodata set that conforms to "GeMS (Geologic Map Schema)--a standard format for the digital publication of geologic maps," available at http://ngmdb.usgs.gov/Info/standards/GeMS/. Metadata records associated with each element within the geodata set contain more detailed descriptions of their purposes, constituent entities, and attributes. An OPEN shapefile version of the data set is also available. It consists of shapefiles, DBF files, and delimited text files and retains all information in the native geodatabase, but some programming will likely be necessary to assemble these components into usable formats. These metadata were prepared with the aid of script GeMS_FGDC1_Arc10.py, version of 20 July 2020. PROJECTION AND DATUM: All data is in North American Datum 1983 with Universal Traverse Mercator (UTM) projection, zone 16, North.
