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 charact...erization 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.

SAND_GRAVEL_RESOURCES_IN is a polygon shapefile that identifies sand and gravel permissive tracts in the surficial unconsolidated deposits of Indiana. Permissive tracts have been defined by the U.S. Geological Survey (Open File Report 95-681, Singer, D.A., 1993, Basic concepts in three-part quantitative assessments of undiscovered mineral resources: Nonrenewable Resources, v. 2, no. 2, p. 69-81) as "areas where the geology permits the existence of mineral deposits (mineral resource potential) of a specific type... Noting that the possibility of the occurrence of the specified deposit type (mineral resource) outside the permissive tract should be negligible." This shapefile provides an approximate economic ranking of the sand and gravel resource potential of each mapped surficial unconsolidated deposit. The resource potential of each map unit within the mapped surficial unconsolidated deposits is ranked as a "potential," "low potential," or "not a potential" resource. The definitions of these rankings are derived from Gray, H. H., 1973, Properties and uses of geologic materials in Indiana: Indiana Geological Survey Regional Geologic Map Supplementary Chart 1 and Carr, D. D., and Webb, W. M., 1970, Sand and gravel resources of Indiana: Indiana Geological Survey Bulletin 42-D, 31 p. "Potential resource" indicates that the surficial unconsolidated deposits are likely to contain economic concentrations of sand and gravel, "low potential" indicates that the surficial unconsolidated deposits may contain economic concentrations of sand and gravel, and "not a potential resource" indicates that the surficial unconsolidated deposits do not contain economic concentrations of sand and gravel.
