  • Mitchell, William M. (Indiana Geological Survey, 1993)
    The Indiana Geological Survey (IGS), in cooperation with the Indiana Department of Natural Resources' Division of Oil and Gas, conducted a study of Mississippian and Pennsylvanian aquifers in southwestern Indiana to identify ...
  • McGregor, Duncan J. (Indiana Geological Survey, 1958-12)
    Limestone that is chemically suitable and easily accessible for cement manufacture can be found at many places in Indiana in the Mississippian limestones and to a more limited extent in the Devonian limestones. Clay, shale, ...
  • Friedman, Samuel A. (Indiana Geological Survey, 1960-12)
    Data from coal-test boreholes and outcrops show that channel-fill sandstones occur at 32 localities in western Indiana in the Brazil, Staunton, Linton, Petersburg, and Dugger Formations of middle Pennsylvanian age. These ...
  • Conolly, Carol L.; Rupp, John A. (Indiana Geological Survey, 2001-01)
    This study assesses the coal resources of the Danville and Springfield Coal Members (Dugger and Petersburg Formations, respectively) in Indiana and provides new estimates of the tonnage of coal in the following categories ...
  • Strapoc, Dariusz; Schimmelmann, Arndt; Mastalerz, Maria; Eble, Corland (2007-01-12)
    Coalbed gases and waters from exploratory and production gas wells in the southeastern Illinois Basin were sampled to geochemically assess the origin of coalbed gases, with emphasis on Springfield and Seelyville coal members ...

  • Solano-Acosta, Wilfrido ([Bloomington, Ind.] : Indiana University, 2010-06-01)
    The increasing demand for energy and a growing concern for global warming, owing in part to the steep rise in anthropogenic greenhouse gas emissions, have sparked worldwide interest in clean coal technologies. Although the ...
  • Burger, Ann M.; Rexroad, Carl B.; Schneider, Allan F.; Shaver, Robert H. (Indiana Geological Survey, 1966-05)
    Indiana lies wholly within the Central Lowland Province and thus calls to mind widespread, thin, nearly flat-lying Paleozoic rocks, major unconformities, and extensive plains. These features express epeirogenic submergences ...
  • Canright, James E. (Indiana Geological Survey, 1959-08)
    Plant fossils were first recorded in Indiana by David Dale Owen in l843. Lesquereux's "Description of the Coal Flora of the Carboniferous Formation in Pennsylvania and Throughout the United States," published in 1880, ...
  • Guennel, Gottfried K. (Indiana Geological Survey, 1952)
    In this report the significance of spores in plant life cycles is discussed briefly. The term “miospore” is proposed for fossil spores and spore-like bodies under 200 micra in size. Sampling and coal preparation are outlined, ...
  • Hutchison, Harold C. (Indiana Geological Survey, 1960)
    The Brazil Quadrangles are located in west-central Indiana and comprise an area of approximately 116 square miles. The rocks that crop out in the area belong to the Mansfield, Brazil, Staunton and Linton Formations of the ...
  • Wier, Charles E. (Indiana Geological Survey, 1952)
    The Jasonville quadrangle, located in parts of Clay, Greene, and Sullivan Counties in west central Indiana, contains approximately 58 square miles. The rocks exposed in the quadrangle comprise the Staunton, Linton, Petersburg, ...
  • Gray, Henry H.; Jenkins, Robert D.; Weidman, Robert M. (Indiana Geological Survey, 1960)
    The Huron area is approximately 85 mi. SSW. of Indianapolis and includes approximately 117 sq. mi. of area in the physiographic province known as the Crawford upland. Nearly flat-lying sedimentary rocks of late Mississippian ...
  • Barrett, Edward (State Geologist) (Bloomington, IN: Indiana Geological Survey Press., 1914-08-03)
  • Wier, Charles E.; Wayne, William J. (Indiana Geological Survey, 1953)
    Parke County, which is located about 50 miles west of Indianapolis, has an area of 447 square miles. It is bounded on the north by Fountain County, on the northeast by Montgomery County, on the east by Putnam County, on ...
  • Bundy, Wayne M. (Indiana Geological Survey, 1956-09)
    Most of the iron deposits of Martin and Greene Counties, Ind. , are within the Mansfield formation (lower Pennsylvanian), but small deposits also occur in the Beech Creek limestone (upper Mississippian). Goethite, the major ...
  • Guennel, Gottfried K. (Indiana Geological Survey, 1958)
    Ninety-eight samples were collected for this study at 85 localities in 12 Indiana Counties. Percentage relationships of miospore genera and relative abundances of species were determined for these samples and can be used ...
  • Walker, Frank H. (Indiana Geological Survey, 1959-04)
    This preliminary report on the natural brines of Indiana and adjoining parts of Illinois and Kentucky is a compilation of 473 brine analyses. The analyses were obtained from the files of many companies as well as from ...
  • Gray, Henry H. (Indiana Geological Survey, 1962-11)
    The Mansfield Formation of early Pennsylvanian age crops out in an area of approximately 1,700 square miles in southwestern Indiana. Three-fifths of the formation consists of sandstone; most of the remainder is finer clastic ...
  • Wier, Charles E.; Esarey, Ralph E. (Indiana Geological Survey, 1951-05)
    During the period of oil and gas development in the 1950s, many petroleum geologists became interested in Pennsylvanian stratigraphy in Indiana. They hoped that the attitude of some of the key beds in the Pennsylvanian ...
