Abstract: A survey has been made of the 87Sr/86Sr ratios and the rubidium and strontium concentrations in the different types of geologic materials underlying the Scioto River drainage basin in central Ohio. In the part of the basin north of the limit of maximum glaciation, these lithologies are mostly Paleozoic carbonate rocks and glacial deposits, as well as the soils that have developed on them. These materials have fairly low 87Sr/80Sr ratios of 0.708-0.715. South of the glacial limit, shales are abundant. These shales and the soils developed on them have much more radiogenic ratios of 0.703-0.745. Leaches of the shales and related soils, however, have ratios of only about 0.710-0.713. These data are in full accord with earlier published data and interpretations of the isotope geochemistry of strontium in the Scioto basin.
