Carlson, M. P., 1963. Lithostratigraphy and Correlation of the Mississippian System in Nebraska (GSB-21): 61 pp., size 6" x 9". Description: The purpose of this study was to describe and correlate rocks of Mississippian age within Nebraska. This investigation has been designed to: 1) delineate lithologic subdivisions of the Mississippian in the subsurface of Nebraska; 2) trace these individual units throughout the state, noting extent, thickness, lithologic variations and relationships with underlying and overlying beds; and 3) suggest a tentative correlation of these units with units of the outcrop areas.
