Available in PDF, EPUB and Kindle. Book excerpt: The Ohio Department of Natural Resources, Division of Geological Survey and Indiana Geological and Water Survey have characterized a regional section of the buried Teays-Mahomet (Teays) River Valley system through rotary sonic drilling. The Teays River, once part of a major pre-Quaternary drainage system, was altered and filled with unconsolidated deposits from multiple glacial events. Previous regional mapping efforts in the Teays Valley were limited by the complex and spatially variable nature of the valley's fill, as well as the uncertainty of the valley's local morphology. Passive seismic geophysical methods and pre-existing well log data first were used to locate ideal drilling locations within the buried valley in western Ohio and eastern Indiana. Two continuous cores were drilled through the Teays to allow for detailed description of the valley fill stratigraphy and subsampling for physical and geochemical analyses. This report describes the results of the drilling process and subsequent laboratory analyses.
