The Indiana Geological and Water Survey (IGWS) is a long-standing, state-supported organization benefiting the welfare of the citizens of Indiana since Dr. David Dale Owen was hired to conduct a geological assessment of the state during 1837 and 1838. For most of the 20th century, the IGWS was associated with Indiana University (IU), and in 1993, Indiana statute (IC 21-47-2) formally established the IGWS as part of the university. The IGWS director serves as the state geologist of Indiana. Under the direction of the state geologist, the survey is charged with conducting geological research, providing geological information, data and educational outreach, and maintaining physical and digital geological collections.

Item Aggregate Resources ofthe Big Blue River Valley in East-Central Indiana(Indiana Geological Survey, 1980) Ault, Curtis H.; Moore, Michael C.Quarry and gravel-pit operators in search of new mining sites are faced with a dilemma. How may aggregate producers mine near a city, where most of the product is sold, and still cope with local taxes, environmental laws, and zoning regulations? There is great economic advantage, both to the producer and the consumer, in locating an aggregate plant near an urban center, because aggregate is a heavy, bulky product that is expensive to transport. Unfortunately, aggregate reserves are not always where they are needed. Producers are well aware that while commercial deposits of quarry rock and sand and gravel are common and widespread, they are by no means ubiquitous. Zoning boards have given this fact less than due consideration. Thus arises the dilemma. The most desirable sites, already limited by fixed geologic factors, are further restricted by regulation and competition with other land uses…Item Bedrock geologic map of Indiana(Indiana Geological & Water Survey, 1987) Keller, Stanley J.; Ault, Curtis H.Item Cementing Depths to Protect Coals in Southwestern Indiana(Indiana Geological & Water Survey, 1984) Ault, Curtis H.Item Compendium of Paleozoic Rock-Unit Stratigraphy in Indiana—a Revision(Indiana Department of Natural Resources Geological Survey, 1986) Shaver, Robert H.; Ault, Curtis H.; Burger, Ann M.; Carr, Donald D.; Droste, John B.; Eggert, Donald L.; Gray, Henry H.; Harper, Denver; Hasenmueller, Nancy R.; Hasenmueller, Walter A.; Horowitz, Alan S.; Hutchison, Harold C.; Keith, Brian D.; Keller, Stanley J.; Patton, John B.; Rexroad, Carl B.; Wier, Charles E.Item Crushed Stone Aggregate Resources of Indiana(Indiana Geological Survey, 1971) Carr, Donald D.; French, Robert R.; Ault, Curtis H.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 bound for use as filter stone, flux stone, railroad ballast, riprap, or road metal. Crushed limestone and dolomite, sand and gravel, slag, perlite, and expanded shale are the main natural and fabricated aggregates currently used in Indiana. Some aggregate, such as sand and gravel, requires little or no processing and can be used almost as it is mined, but rock must be crushed and sorted into various desired sizes before it can be used. Many types of rocks can be used for crushed stone aggregate, but limestone and dolomite are used exclusively in Indiana (pl. 1). In this report crushed stone is synonymous with crushed limestone and dolomite. Each type of aggregate has a distinct advantage with respect to cost and availability or to a specific use for which one type is more suited than another. The advantages of crushed limestone and dolomite are that they can be crushed and sized to meet most specifications, the materials are clean and angular and bind well with cementing mixtures, a uniform lithologic composition can be maintained with little or no selective quarrying in many areas, and they are available at low cost in most counties in Indiana. Crushed stone is one of Indiana’s most important mineral commodities, ranking third in annual value behind coal and cement. During 1969 crushed stone production in Indiana totaled 25, 516,000 tons and was valued at $34,418,000.Item Database of Abandoned Industrial Minerals Quarries in Indiana(Indiana Geological & Water Survey, 1994) Hasenmueller, Walter A.; Ault, Curtis H.Item Directory of Crushed Stone, Ground Limestone, Cement and Lime Producers in Indiana(Indiana Geological & Water Survey, 1970-09) Carr, Donald D.; Ault, Curtis H.Item Directory of Crushed Stone, Ground Limestone, Cement, and Lime Producers in Indiana(Indiana Geological & Water Survey, 1980-10) Carr, Donald D.; Ault, Curtis H.Item Directory of Crushed Stone, Ground Limestone, Cement, and Lime Producers in Indiana(Indiana Geological & Water Survey, 1972-12) Carr, Donald D.; Ault, Curtis H.Item Directory of Crushed Stone, Ground Limestone, Cement, and Lime Producers in Indiana (August, 1977)(Indiana Geological & Water Survey, 1977) Ault, Curtis H.; Carr, Donald D.Item Discovery of Thick Reefal Limestone in Howard County, Indiana(Indiana Geological & Water Survey, 1990) Ault, Curtis H.; Ennis, Margaret V.Item Exposures of Silurian Reefs in Indiana(Indiana Geological & Water Survey, 1992) Ault, Curtis H."Numerous Indiana geologists, quarries, and others have searched for, admired, photographed, climbed, sampled, drilled, cored, analyzed, and mined the exposed Silurian reefs of Indiana. From before 1862, when Richard Owen described the curious tilted outcrops of reefal limestone in several places in northern Indiana, pioneer geologists and others speculated on the origin of the reefs with ideas of structural deformation, arches, false bedding, and even volcanism. These imaginative ideas were generally set to rest in 1928 (Cumings and Shrock, 1928a, 1928b). Since then much more has been learned about the reefs (Shaver, 1991), numerous additional reefs have been discovered (Ault and others, 1976, 1992), and their practical usefulness for many chemical and physical products has expanded dramatically. From early pioneer times, quarries in northern Indiana, especially in the Wabash Valley, mined the reefs for roadstone and railroad ballast and burned the stone to make lime for mortar, agricultural lime, and whitewash. The reef rock was also used with other Silurian carbonate rock for foundation stone, flagging, and building stone."Item Faulting and Jointing in and Near Surface Mines of Southwestern Indiana(Indiana Geological & Water Survey, 1985) Ault, Curtis H.; Sullivan, Dan M.Item Faulting in Southwest Indiana(Indiana Geological & Water Survey, 1982) Ault, Curtis H.; Sullivan, Dan M.; Tanner, GeorgeItem Geology for Environmental Planning in Marion County, Indiana(Indiana Geological Survey, 1980) Hartke, Edwin J.; Ault, Curtis H.; Austin, George S.; Becker, Leroy E.; Bleuer, N.K.; Herring, William C.; Moore, Michael C.Marion County is the center of a large and rapidly growing urban-industrial complex in the heartland of Indiana. The boundaries of the county and of Indianapolis, the state capital, are the same as a result of the UNIGOV concept. The rapid growth of Indianapolis and its suburbs makes effective land-use planning important for Marion County. This report is designed to provide information, based on the geologic setting of the area, that can be used for effective and environmentally sound development of the county.Item Map of Indiana Showing Bedrock Units Containing Thick Deposits of Limestone and Dolomite and Locations of Coal-Fired Electric Power Plants and Crushed-Stone Mines.(Indiana Geological & Water Survey, 1993) Ault, Curtis H.Item Map of Indiana showing directions of bedrock jointing(Indiana Geological & Water Survey, 1989) Wilson, Amanda; Ault, Curtis H.Item Map of Indiana showing elevations or thickness of overburden on selected rock units containing thick deposits of limestone and dolomite(Indiana Geological & Water Survey, 1993) Ault, Curtis H.Item Map of Indiana showing locations of coal-fired electric power plants, crushed-stone mines, and federal and state highways(Indiana Geological & Water Survey, 1994) Ault, Curtis H.Item Map of Indiana Showing Thickness of Silurian Rocks and Location of Reefs and Reef-induced Structures(Indiana Geological & Water Survey, 1976) Becker, Leroy E.; Droste, John B.; Keller, Stanley J.; Shaver, Robert H.; Ault, Curtis H.
