F, Appendix 7, PP1625-C, and used in this study of the Fire Clay coal zone. That dataset is a compilation of data from the U.S. Geological Survey's (USGS) National Coal Resources Data System (NCRDS) USCHEM (U.S. geoCHEMical), and the Kentucky Geological Survey (KGS) Kentucky Coal Resources Information System (KCRIS) databases. The metadata file for the complete dataset is found in Chap. F, Appendix 8, PP1625-C (please see it for more detailed information on this geochemical dataset). This subset of the geochemical data for the Fire Clay coal zone includes ash yield, sulfur content, SO2 value, gross calorific value, arsenic content and mercury content for these records, as well as the ranking of these values, which is described later under the attributes in this metadata file. Analytical techniques are described in the references in Chap. F, Appendix 9, PP1625-C. The analytical data are stored as text fields because many of the parameters contain letter qualifiers appearing after the numerical data values. The following is a list of the possible qualifier values: L - less than, G - greater than, N - not detected, or H - interference that cannot be easily resolved. Not all of these codes may be in this database. Purpose: The purpose of Professional Paper 1625-C is to release the interpretation of assessment and modeling data for the top-producing coal beds in the northern and central Appalachian Basin coal regions. The dataset has been generalized and is useful only in regional studies. Individuals who do not have an internet connection to access the detailed data coverages interactively through GeoDE or who cannot use the ARC/INFO export covers provided on Disc 2, PP1625-C, can use this coverage to obtain limited information on the Fire Clay coal zone. The presented data for the Fire Clay coal must be considered provisional, because the correlation of the zone continues to be evaluated in West Virginia.

Samples were submitted (date of submittal stored as SUBDATE field in USCHEM database) and analyzed for the Fire Clay coal zone through the cooperation of coal geologists (primary contacts listed) at the West Virginia Geological and Economic Survey (William Grady), the Virginia Division of Mineral Resources (James Lovett), the Kentucky Geological Survey (Cortland Eble), and U.S. Geological Survey (staff) [WVGES, VDMR, KGS, and USGS, respectively]. Additional data were obtained from the KGS Kentucky Coal Resources Information System (KCRIS) database for this Study. [See references, Chap. F, Appendix 9, PP1625-C]. It is recommended that newer data be obtained from the State geological surveys that are the sources of the original information in this study. Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Deductive_Estimate: The accuracy of the geochemical data for each element can be found in descriptions of analysis techniques listed in references [Chap. F, Appendix 9, PP1625-C]. These references include: ASTM, 1996; Golightly, D.W., and Simon, F.O., 1989; and Swanson, V.E., and Huffman, Jr., C., 1976. Logical_Consistency_Report: For differences in measured data values arising from differences in analytical methods, see the following references: ASTM, 1996; Golightly, D.W., and Simon, F.O., 1989; and Swanson, V.E., and Huffman, Jr., C., 1976; [Chap. F, Appendix 9, PP1625-C]. Completeness_Report: All available correlated public data (at the time of compilation of this database) for the Fire Clay coal zone were compiled for this study. The state of Tennessee is excluded. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Several data sources were used as input to this data set. Original data were stored in NCRDS in latitude/longitude coordinates with a possible precision of decimal seconds. The latitude/longitude coordinates from KCRIS were also stored in decimal degrees. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The raw input data represent thickness measurements from a variety of data types: cores, outcrop, road cuts, and others. The original errors associated with these measurements are unknown. Errors may arise from the differences in the judgment of geologists in the differentiation between coal, bone and partings. Bone coal and partings > 3/8 in thick were assumed to be excluded from the samples during sampling. Thickness data were used in averaging the analytical data from partial (bench or lithotype) coal samples to represent the whole coal bed. Errors may also arise from miscorrelations of the coal beds. Lineage: Process_Step: Process_Description: This dataset was compiled as a selected subset of the complete dataset found in Chap. F, Appendix 7, PP1625-C. This subset of data contains all the data having latitudes and longitudes (point data which are capable of being mapped). Ash yield, sulfur content, and SO2 content data are classified into categories of low (> 0 - <= 8 percent ash; > 0 - <= 1 percent sulfur; > 0 - <= 1.2 lbs SO2 per million Btu), medium (> 8 - <= 15 percent ash; > 1 - < 3 percent sulfur; > 1.2 - <= 2.5 lbs SO2 per million Btu ), and high (> 15 percent ash; >= 3 percent sulfur; > 2.5 lbs SO2 per million Btu). Ash yield and sulfur content are classified according to Wood and others (1983) [Chap. B, Appendix 1, PP1625-C]. SO2 content is classified according to past and present Clean Air Act Amendments [U.S. Statutes at Large, 1990; (See references, Chap. F, Appendix 9, PP1625-C)]. Calorific value, arsenic, and mercury are classified into 5 data categories, or quintiles, each representing 20 percent of the data values. Rankings of low, med low, medium, med high, and high are assigned to the quintile rankings based on the lowest to highest values in each 20 percent of the data.
