  • Rooney, Lawrence F. (Indiana Geological Survey, 1970)
    Most dimension limestone in Indiana is produced from the Salem Limestone (fig. 1). A significant amount is produced from the Laurel Member of the Salamonie Dolomite, the Louisville Limestone, and the Geneva Dolomite. ...
  • Utgaard, John; Perry, Thomas G. (Indiana Geological Survey, 1960)
    Fenestrate bryozoans are particularly abundant in shale and argillaceous limestone beds in the upper part of the Glen Dean Limestone (middle Chester) of late Mississippian age In south-central Indiana. Several hundred ...
  • 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, ...
  • Thornbury, William D.; Deane, Harold L. (Indiana Geological Survey, 1955)
    Most of the geomorphic features of Miami County are of glacial origin or are glacial deposits that were modified by postglacial erosion. Three major and nine smaller valleys were sluiceways for glacial melt waters. The ...
  • 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 ...
  • Carr, Donald D. (Indiana Geological Survey, 1973)
    Oolitic limestones constitute 22 percent of the Ste. Genevieve and Paoli Limestones (Mississippian) in seven cores equally spaced along the length of outcrop in southern Indiana; which lies on the eastern margin of the ...
  • Wayne, William J.; Thornbury, William D. (Indiana Geological Survey, 1951)
    Most of the topographic features of Wabash County are of glacial origin or are glacial deposits eroded by postglacial streams. Shales, limestones, and dolomites, all Silurian, are exposed only along some of the deeper ...
  • Thornbury, William D. (Indiana Division of Geology, 1950)
    Lacustrine plains of two distinct ages and origins occur in southern Indiana. One system of lakes of Illinoian age developed as marginal lakes because of the ponding of the southwest drainage by the lobe of Illinoian ice ...
  • McGregor, Duncan J. (Indiana Geological Survey, 1963)
    High-Calcium limestone and dolomite suitable for industrial use exist in Indiana. Selected measured stratigraphic sections and chemical and spectrographic analyses are used to evaluate high-Calcium limestone and dolomite. ...
  • St. Jean, Joseph, Jr. (Indiana Geological Survey, 1957)
    This report describes 23 species belonging to 14 genera of lower middle Pennsylvanian Foraminifera from a single outcrop in Dubois County, Ind. Three new species of Endothyra and one of Endothyranella are described. Seven ...
  • Erd, Richard C.; Greenberg, Seymour S. (Indiana Geological Survey, 1960)
    Undisturbed Paleozoic sediments form the bedrock surface of Indiana. The most common minerals in these sediments are calcite, clay minerals, dolomite, glauconite, goethite, gypsum, hematite, limonite (hydrous iron oxides), ...
  • 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 ...
  • Wayne, William J. (Indiana Geological Survey, 1960)
    The system of stratigraphic classification used in North America for all sedimentary rock units except nonmarine deposits of the Pleistocene Series established groups, formations, and smaller units based on objectively ...
  • Carr, Donald D.; Webb, William M. (Indiana Geological Survey, 1970)
    Sand and gravel are unconsolidated granular materials resulting from the natural disintegration of rocks. Unlike most other mineral commodities they are defined in terms of particle size rather than mineral or chemical ...
  • Pinsak, Shaver, Robert H. Arthur P. (Indiana Geological Survey, 1964)
    The Silurian rocks in northern Indiana include, in ascending order, the Brassfield Limestone (lower Silurian), the Salamonie Dolomite, the Louisville Limestone, and the Wabash Formation, all of the Niagaran Series (middle ...
  • Wood, Joseph M. (Indiana Geological Survey, 1968)
    Plant macrofossils are found in shales, ironstone concretions, and sandstones that lie immediately above the Lower Block Coal near Stanley Cemetery in Greene County, Ind. The Lower Block Coal lies at the base of the Brazil ...
  • Rexroad, Carl B. (Indiana Geological Survey, 1967)
    Abstract Conodonts were collected from 49 sections of the Brassfield Formation (Brassfield Limestone) in its outcrop belt around the Cincinnati Arch in Indiana, Kentucky, and Ohio. Thirty-four indigenous species represent ...
  • Nicoll, Robert S.; Rexroad, Carl B. (Indiana Geological Survey, 1968)
    Zonation established by study of the conodont faunas of the Lee Creek Member (new member) of the Brassfield Limestone and of the Salamonie Dolomite, both of Silurian age, from 42 sections in southeastern Indiana and ...
  • Wier, Charles E. (Indiana Geological Survey, 1961)
    Middle and Upper Pennsylvanian rocks in Southwestern Indiana were studied using outcrops, cores, driller's logs of core tests, and electric logs of oil tests. These rocks are sedimentary in origin. Clastic rocks--sandstone, ...
