Illinois State Geological Survey

Illinois State Geological Survey

Our Mission

To provide the citizens and institutions of Illinois with earth science research and information that are accurate, objective, and relevant to our State's environmental quality, economic prosperity, and public safety.

Our Vision

To build upon our stature as a premier state geological survey by upholding the highest standards for scientific research, service to our constituents, and professionalism in all our activities. To serve as the North American model for multi-disciplinary geological survey research in the twenty-first century.

The Illinois State Geological Survey (ISGS) is part of the Institute of Natural Resource Sustainability at the University of Illinois at Urbana-Champaign. The Survey is located in the Natural Resources Building on the University's 700-acre campus. This central Illinois location (map and driving directions) is just 130 miles south of Chicago. It is a cultural and educational center that is ranked as one of the top ten "high-tech" cities in the U.S. The area provides the attractive combination of small-city convenience and quality of life with ready access to world-class laboratory and academic facilities, Big Ten athletic events, and internationally acclaimed cultural opportunities.

The ISGS is a premier state Geological Survey serving the needs of Illinois with earth science information relevant to the State's environmental quality, economic vitality, and public safety. Some 200 scientists and technical support staff conduct basic and applied research in geology, compile geologic maps, and gather and manage the state's geological data to provide information to industry, governmental agencies and the public about the geology and mineral resources of Illinois.

Survey staff may conduct joint research projects, supervise graduate studies, and teach courses through joint appointments with the University.

Hand Samples stored in main Annex building, mostly from Illinois and neighboring states. Includes minerals, geodes, outcrop samples, sed. structures, industrial minerals, ore, and various personal and donated collections. Approx. 475 drawers, shelves, and bins These samples are loosely organized and located in numerous places throughout the Annex complex. Some are still in original bulk collection bags, others in drawers, bins, or shelves. Most are not cataloged. Some outcrop samples are cataloged, however about 30 shelves of boxed and numbered outcrop samples have no known catalog.
Fossil samples stored in the main Annex building cabinets. Primarily invertebrates collected by survey staff, this collection is a good representation of fossils from geographic areas and stratigraphic units in Illinois. The majority of samples are not cataloged; however most are physically arranged chronostratigraphically. Approximately 150,000 samples total, primarily Cambrian (1500), Ordovician (15,000), Silurian (17,000), Devonian (10,000), Mississippian (15,000), Pennsylvanian (77,000), and Tertiary/Cretaceous (100). Approximately 10,000 specimens are arranged by taxonomic group including brachiopods (7500), cephalopods (1000), and trilobites (2000).
