Marcellus thickness contours are derived from Plate 7 "Thickness of Highly Radioactive Shale in Hamilton Group" from Joseph F. Schwietering, "The Occurrence of Oil and Gas in Devonian Shales and Equivalents in West Virginia", March 1981. WVGES Open File Report OF-8608
To show thickness contours for the Marcellus Shale of the Hamilton Group in West Virginia
publication date
The intended use is for small scale map rendering (i.e., "state size" or 1:~1,500,000) and not for any serious analysis, especially on large scale mapping (i.e., county or quadrangle size or anything below 1:1,500,000). Permission to reproduce this material is granted if acknowledgment is given to the West Virginia Geological and Economic Survey.

A TIFF was generated from the 8.5" x 11" inch PDF report. The TIFF was georeferenced and rectified with ESRI ArcGIS Desktop (i.e., "ArcMap") version 10.0 using first order polynomial (Affine) and about 35 reference points. Lines were created from a zoomed in range of 20,000 to 40,000 and drawn at center points of the pixel width of the darkest pixels from the TIFF line.

DISCLAIMER REGARDING THE RELEASE OF DATA AND USER REQUIREMENTS The West Virginia Geological and Economic Survey (WVGES) makes basic data available to the public under the following conditions: 1. We believe the data from WVGES to have been generated and assembled with a high degree of professionalism, accuracy, and precision for the purposes for which they were originally intended. In this context, "data" refer to numerical and textual data (such as in the "pipeline" application), digitial data (such as .las files), digital images (such as digital photographs), scanned records (such as completion reports), and spatial data (such as shapefiles). Some data have been compiled from other sources and the WVGES accepts no responsibility for any inaccuracies in those data. Therefore, we cannot and do not, either implicitly or explicitly, guarantee the accuracy, precision, or completeness of the data. 2. Neither the WVGES nor its staff members are liable or responsible for any damage or loss resulting from the use of the data or from inaccuracies contained in the data. 3. These data are provided as a service to the State of West Virginia through the WVGES for the purpose of research and development efforts. Final use of these data is the sole responsibility of the user. 4. We encourage you to report any problems, inconsistencies, or errors noted in using these data to the Information Services Program, so that we can correct them and provide even better service.
