  • 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 ...
  • Patton, John B.; Perry, Thomas G.; Wayne, William J. (Indiana Geological Survey, 1953-05)
    This field trip guidebook discusses the stratigraphy and paleontology of the Ordovician rocks exposed in southeastern Indiana. Ordovician rocks in southern Indiana are exposed in a region that is stimulating to physiographers ...
  • 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 ...
  • Gray, Henry H.; Dawson, Thomas A.; McGregor, Duncan, Jr.; Perry, Thomas G.; Wayne, William J (Indiana Geological Survey, 1957-10)
    The purpose of this field conference is to acquaint participants with strata that are associated with the Mississippian-Pennsylvanian boundary in southwestern Indiana. Criteria which aid in distinguishing between Mansfield ...
  • Perry, Thomas G.; Smith, Ned M.; Wayne, William J. (Indiana Geological Survey, 1954-05)
    This field conference was organized to promote a better understanding of the geology of the Salem limestone and associated formations and the physiography of the region in which these rocks are exposed. The conference has ...
  • Murray, Haydn H. (Indiana Geological Survey, 1955-09)
    Devonian rocks in southern Indiana have presented many problems of correlation; their stratigraphy has been studied during recent years by T. A. Dawson and John B. Patton. General conditions of sedimentation of the Devonian ...
  • Esarey, Ralph E.; Malott, Clyde A.; Galloway, Jesse J. (Indiana Division of Geology, 1947)
    This conference was planned to provide an opportunity to observe and discuss outcrops of Silurian and Devonian rocks in southeastern Indiana. The broad aspects of the stratigraphy and fauna were emphasized since most persons ...
  • Esarey, Ralph E.; Bieberman, Doris F. (Indiana Division of Geology, 1948-05)
    In response to popular demand, the Silurian formations and associated reef structures of northern Indiana were chosen as the subject for the 1949 Field Conference. The numerous quaquaversal structures in the Niagaran of ...
  • Esarey, Ralph E.; Bieberman, Doris F.; Bieberman, Robert A. (Indiana Division of Geology, 1950-05)
    The Mississippian-Pennsylvanian unconformity is the most pronounced and extensive break in the Paleozoic rocks of the Eastern Interior Basin. During the long erosional interval Mississippian beds were truncated and a ...
  • Shaver, Robert H. (Indiana Geological Survey, 1961-05)
    The Tenth Indiana Geologic Field Conference treats the stratigraphy of the Silurian rocks that lie between the Cincinnatian rocks and the bedrock surface in the rectangular area whose corners are defined by Cass, Allen, ...
  • Mallot, Clyde A.; Esarey, Ralph E.; Bieberman, Doris F. (Indiana Division of Geology, 1948-05)
    This field trip was organized to observe and discuss outcrop of Upper and Middle Mississippian age in Indiana. These formations are of special economic interest because the greater part of petroleum, agricultural limestone, ...
