Digital Representation of Selected Isopach and Geologic Maps from U.S. Geological Survey Paleotectonic Publications

Important hydrological and geotechnical information from U.S. Geological Survey (USGS) reports detailing selected paleotectonic geologic periods, including the Jurassic (McKee and others, 1956), Triassic (McKee and others, 1959), Permian (McKee and McKee, 1967), Pennsylvanian (McKee and Crosby, 1975), and Mississippian (Craig and Connor, 1979), were digitized from scanned plates. Discrete well points attributed with a thickness value and isopach contours were captured and, along with geologic contact information from the Geologic Map of North America (GMNA) (Garrity and Soller, 2009), were used to interpolate geologic thickness for each period.
Data available in this data release include 5 compressed (.zip) geodatabases (.gdb).
