1926, Illinois State Geological Survey
1985, Illinois State Geological Survey
In connection with geologic and other geochemical studies of the New Albany Shale Group (Devonian-Mississippian) in the Illinois Basin, 392 shale samples were analyzed for major and minor element composition, and 38 trace elements. There were 230 samples from 15 cores and 162 well cuttings. The...
1985, Illinois State Geological Survey
Surficial electrical resistivity and shallow geothermic surveys were conducted along the western, southern, and northern sides of the Sheffield low-level radioactive waste-disposal site in Bureau County, Illinois. The purpose of these surveys was to find and delineate the boundaries of water-...
1983, Illinois State Geological Survey
Surficial electrical resistivity and shallow geothermic surveys were conducted in an area just east of the Sheffield low-level radioactive waste disposal site in Bureau County, Illinois. The purpose of these surveys was to find and delineate the boundaries of water-bearing, coarse-grained glacial...
1981, Illinois State Geological Survey
An electrical earth resistivity survey was conducted over an area adjacent to the Sheffield low-level radioactive waste disposal site in Bureau County, Illinois. The purpose of the survey was to determine the extent of a deposit of sand belonging to the Toulon Member of the Glasford Formation that...
1989, Illinois State Geological Survey
Because of declining water levels and high radium content in water from deep bedrock sandstone aquifers, the Village of Montgomery is interested in developing alternate water sources to meet future needs. Shallow aquifers in the glacial drift and upper bedrock are among the sources being considered...
1988, Illinois State Geological Survey
In this study we tested an ultrafine coal cleaning approach combining rapid thermal-chemical comminution and efficient physical separation. The Aggregate Flotation (AF) physical coal cleaning process, developed at the Illinois State Geological Survey (ISGS), was used to treat products obtained from...
1986, Illinois State Geological Survey
Petrographic, mineralogic, and minor and trace element compositions of the first five samples in the Illinois Basin Coal sample Program (IBCSP) were determined, and an information system for IBCSP was established on a mainframe computer at the University of Illinois. The information is accessible...
1985, Illinois State Geological Survey
The Information System on Chemistry of Illinois Coal (ISCIC) is a computer database of proximate and ultimate analyses and other test results on Illinois coal. The ISCIC operates on a University of Illinois computer (Cyber 175) located in Urbana. At present the data file consists of chemical...
1984, Illinois State Geological Survey
One gram samples of 13 high-volatile bituminous coals from Illinois, spiked with a small amount of radioactive synthetic pyrite, Fe<sup>35</sup>S<sub>2</sub>, or with a small amount of irradiated 1.6 specific-gravity sink fraction prepared from five of the coals, were...
1983, Illinois State Geological Survey
Analytical data are given for 67 chemical elements and related parameters and 8 mineralogical components in 102 newly collected samples of coal from the Springfield and Herrin Coals, the two principal coal seams mined throughout the Illinois Basin Coal Field. (This field extends from Illinois into...
1989, Illinois State Geological Survey
The 1988-90 drought in central Illinois resulted in alarmingly low water levels in reservoirs supplying water to the City of Bloomington. At the request of the city, the Illinois State Geological Survey conducted geophysical investigations to locate potential groundwater resources in the vicinity...
1981, Illinois State Geological Survey
A number of communities in Saline County and western Gallatin County, Illinois, experience periodic water shortages. These communities obtain their water supplies from a variety of sources, each inadequate to supply increasing demands. A comprehensive hydrogeologic study of this region was...
1987, Illinois State Geological Survey
The Illinois Department of Transportation (IDOT) initiated the freeze-thaw test (ASTM C666-77) as an additional quality control in order to eliminate "D-cracking" from Portland cement concrete highways in Illinois. The objective of this joint research project of the Illinois State...
1981, Illinois State Geological Survey
Failure of current trench covers in the humid eastern portion of the United States to prevent tritium and other radionuclide migration has prompted research into methods of reducing infiltration by modified trench covers. This report includes a discussion of present practices and a review of the...

About the Geological Surveys Database
https://statesurveys.americangeosciences.org

As of July 2018, the Geological Surveys Database replaces the Critical Issues Research Database, providing an improved portal for decision makers and others to locate and comprehensively search state geological survey publications and U.S. Geological Survey factsheets.

The Geological Surveys Database provides full-text searching of publications meaning that users can not only search metadata fields (i.e., title, author, notes, etc.), but also search against the entire text of the publications in the database in order to find the information they are seeking. The database also features interactive geographic searching of publications that have geographic coordinates, browsing of publications, faceted searching, and more.

Record display views include robust metadata that is based on a combination of GeoRef metadata that is supplemented with additional metadata from the state geological surveys and U.S. Geological Survey, links to state geological survey websites, suggestions for similar items, and a map display of associated geographic metadata coordinates.

The Geological Surveys Database also provides a wide array of user features including the ability to export citations, create user accounts to save queries, citations and create curated lists, add comments and custom tags to records in the database, and more.

The Geological Surveys Database is a collaborative effort between the American Geosciences Institute and U.S. state geological surveys to help increase the discoverability and use of geological survey publications by decision makers as they address issues at the intersection of the geosciences and society.
