This map presents basic bedrock geological information that contributes to the characterization of potential mineral resources and bedrock aquifer systems in Bartholomew County. The map is a synthesis of archived public domain geological data obtained from many different sources, original data obtained from field work conducted by the authors, and contract drilling supported by project funds. Archive data sources include petroleum-well records, water-well records, engineering borings, refraction seismic surveys, soil surveys, the field notes and field maps of geologists who previously worked in or near Bartholomew County, and the geological literature. Project data includes observations at natural and man-made exposures, contracted rotary drilling, contracted core drilling, and horizontal-to-vertical spectral ratio geophysical surveys conducted by the authors.
