Geology and coal deposits of the Shelburn quadrangle, Sullivan County, Indiana

The Shelburn quadrangle is the fifth in a series of quadrangle maps prepared as a part of a program by the Geological Survey, Indiana Department of Conservation, and the U.S. Geological Survey to appraise the coal resources of Indiana.  The field work was done by the writer, assisted by Dick S. Horton and Robert E. Hurley, during the summer of 1949 and for a short period during the summer of 1950.  Data on mines, records of past production, and records of exploratory drilling for coal and oil were provided by the operators in the quadrangle, whose help and advice has been most helpful in the preparation of this report.  The Indiana Bureau of Mines and Mining provided much valuable information on abandoned mines in the quadrangle.
