Coal Mines

The map below displays quadrangle boundaries in St. Clair County for which the ISGS has completed studies.

	How To Use This Map First locate your area of interest on the map. If this area is located within a quadrangle displayed on the map, please see the quadrangle study for a more detailed description of coal mines. If a quadrangle study is not available for your area of interest, please see the county map and directory. Scroll down to find links to the quadrangle studies and county maps.
Quadrangle Studies

Quadrangle Maps and Directories located in St. Clair County

These selected 7.5-minute quadrangle maps are available online as PDF versions and show active and abandoned mines and their known extent on a topographic map base which includes township, range, and section lines and surface features such as roads, towns, lakes, and rivers. The mines are color-coded by mining method and the relative precision and completeness of the source map used for the mine boundary are indicated. Scale 1:24,000. Accompanying each map is a directory that gives a brief history of mining on the quadrangle and lists for each mine the location of mine opening and tipples; the name, thickness, and depth of seams mined; production history; geologic problems reported; company names; mine names and numbers; type of mine; years operated; coal seam mined; and mine location.

Coal Logs

St. Clair County Coal Logs - PDF file generated 10/29/2008
The .PDF file contains non-confidential coal log descriptions from the Coal Section's stratigraphic database in the county listed. Coal logs are sorted by township/range and section.

You can download the raw .dbf files from which the entire stratigraphic database is derived (if such files are what you really want; most users will only want and need the .PDF files).

Each PDF file has a summary sheet that contains an overview of data and geology for the county. Each coal log has a "header" element that contains location information, log type, log source and other information.

This log is from a borehole located in Saline County, Township 7 South, Range 6 East, northwest quarter of the southeast quarter of section 35, 330 feet from the South section line, and 330 feet from the West section line. North American Datum 1983 (NAD83) Longitude/Latitude coordinates in decimal degrees are also provided.

Beneath the header is information on the geology for that data point. The Coal Section stratigraphic database from which this .PDF file is derived is a multi-project database which contains drill hole and outcrop descriptions of Pennsylvanian stratigraphy in Illinois. Consequently, the level of detail and accuracy in the data and their interpretation vary (sometimes widely, ) with the geologist, project type, or original data source. Multiple descriptions of a particular location may be present. Note that both the coal stratigraphic database and this .PDF listing are only a subset of the total amount of data available from the ISGS Geologic Records Library archives, and reflect only coal-specific data and interpretations of past and present Coal Section geologists. They are not a comprehensive listing of all data that may be available from the ISGS.
