  • Rooney, Lawrence F.; Carr, Donald D. (Indiana Geological Survey, 1971)
    The title of this report as first proposed was "What a Consulting Geologist Should Know About Industrial Limestone" because this effort was born of a request from the Indiana-Kentucky Geological Society, Inc., for a refresher ...
  • Harrison, Jack L.; Murray, Haydn (Indiana Geological Survey, 1964)
    Modern concepts of clays as assemblages of discrete minerals form the basis for the first reevaluation of the clays and shales of Indiana since 1933. Brief explanations of the fundamentals of clay mineralogy and the major ...
  • Shaver, Robert H.; Burger, Anne M. (Indiana Geological Survey, 1970)
    The Geologic Names Committee of the Indiana Geological Survey has maintained for several years tables of the more important rock- and time-stratigraphic names that have been used in Indiana. These tables show classification ...
  • Orr, R. William (Indiana Geological Survey, 1971)
    Study of the stratigraphic distribution of 20 species of the platform genera Icriodus, Polygnathus, Palmatolepis?, and Schmidtognathus at 11 subsurface localities in northern Indiana and at 10 supplementary outcrop localities ...
  • Horowitz, Alan S. (Indiana Geological Survey, 1965)
    Twenty-three species and eight nomina aperta of crinoids from the Glen Dean Limestone (middle Chester) are assigned to the genera Agassizocrinus Owen & Shumard, Aphelecrinus Kirk, Eupachycrinus Meek & Worthen, Hypselocrinus ...
  • Carr, Donald D.; French, Robert R.; Ault, Curtis H. (Indiana Geological Survey, 1971)
    Mineral aggregate is an aggregation of mineral material, such as crushed rock, expanded shale, perlite, sand and gravel, shells, or slag. It is sometimes bound with such material as cement or asphalt or is sometimes not ...
  • French, Robert R. (Indiana Geological Survey, 1967)
    Devonian and Silurian carbonate rocks exposed on the crest and flanks of the Cincinnati Arch provide most of the raw material for the crushed stone industry of Indiana. The present northwest-southeast structure has controlled ...
  • 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 ...
  • 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), ...
  • 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 ...
