They present interpretations of the geology of the area and are based on available data. However, these interpretations are based on data that may vary with respect to accuracy of geographic location, type, quantity, and reliability, as they were supplied to the Illinois State Geological Survey. Consequently, the accuracy of the interpreted features shown in these files is subject to the limitations of the data and varies from place to place. Contoured features less than 7 million square feet (about 1/2 mile square) in area may not be accurately portrayed or resolved. This data set provides a large-scale conceptual model of the geology of the area on which to base further work. These data are not intended for use in site-specific screening or decision-making. Data included in this map are suitable for use at a scale of 1:100,000. The Illinois State Geological Survey and the University of Illinois make no guarantee, expressed or implied, regarding the correctness of the interpretations presented in this data set and accept no liability for the consequences of decisions made by others on the basis of the information presented here. © 2009 Board of Trustees of the University of Illinois.

The coal crops out along the margins of the Illinois Basin and reaches a maxi- mum depth in Illinois of about 1,200 feet. (See Fig 1. and Fig 2.) The Danville Coal is in the Shelburn formation which is part of the Desmoninesian Series. The Danville Coal has been mined in Liv- ingston, McLean, La Salle, and Marshall Counties in addition to Vermilion County. In most of the remainder of the state it is a thin coal, generally a few inches to less than 3 feet thick. The Danville Coal is generally overlain by the Farmington Shale Member of the Shelburn Formation, relatively thick underclay. At the type locality in Vermillion county, the Danville Coal is 6 feet thick and occurs 20 feet above the Herrin Coal. (Hop- kins, 1968 - B95). (See Fig 4.) The original resource of Dan- ville Coal in the State of Illi- nois totals 19.6 billion tons, of which 0.2 billion have been 0 50 100 Miles Danville Coal Extent of Pennsylvannian System ± Illinois Indiana Kentucky mined. Approximately 23% of the original Danville Coal resources, 4.5 billion tons, are considered available for mining. (See Fig 3.) Available means that the surface land-use and geologic conditions related to mining of the deposit (e.g. thickness, depth, in-place tonnage, stability of bedrock overburden) are comparable to other coals currently being mined in the state. Of these re- sources, 4 billion tons occur in coal 42 to 66 inches thick and 0.4 billion tons occur in thicknesses greater than 66 inches. The Danville Coal has been mined in Illinois for over 100 years, but only about 1% of the original resource has been depleted. The most extensive area of mining was in east-central Illinois near the ci ty of Danville where the coal has been mined by both surface and under- ground methods. Except for mines in east-central Illinois, most large surface mines recover the Danville Coal only as part of their opera- tion to remove over- burden to mine the underlying Herrin Coal. In many cases, the Danville seam has been considered to be too thin or too poor in quality to jus- tify recovery and was simply discarded in References: - Handbook of Illinois Stratigraphy, 1975, Illinois State Geological Survey Bulletin 95, 261p. - Christopher P.
