This report includes the geologic, geographic, and chemical information for samples of carbonate and associated rocks from Orange County, Indiana, presented in a tabular format. The tables were generated from the carbonate rock database which is being compiled for the entire state of Indiana. The chemical analyses are for samples obtained since 1947 by geologists with the Indiana Geological Survey (IGS). The purpose of this publication is to present the locations, units sampled, and the chemical analyses, if available, of carbonate rocks within the county. All the analyses were performed by IGS staff and, although some of the data tabulated here have been previously published, no references are given with the individual analyses to indicate such prior appearance. Written descriptions of the samplet sites are available as open-file reports in the Industrial Minerals Section.
