Methodology
  • The Bedrock Geologic Map of the Southern Half of the Knox 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 versions 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.
Description
  • The Bedrock Geologic Map of the Southern Half of the Knox 30- X 60-Minute Quadrangle was created to provide digital access to the bedrock geology of southern half of the Knox quadrangle in northern Indiana. This geodatabase presents basic bedrock geological information that contributes to the characterization of potential mineral resources and bedrock aquifer systems. 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 petroleum-well records, water-well records, refraction seismic surveys, and the geological literature. Project data includes measurements from quarry exposures, drill cores, drill cuttings, geophysical logs, chemostratigraphic analysis via portable X-ray fluorescence and stable isotope ratio mass spectrometry, conodont biostratigraphy, and horizontal-to-vertical spectral ratio geophysical surveys. 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.
