Coal resource information. Volume 2, Part 2. Annotation of selected sources. Final report

For volume 2 part 2, 352 documents were selected for an annotated bibliography on coal resource information. The documents were chosen to ensure representation of all 37 coal-bearing states. Documents selected for annotation were those with more recent information about the quantity and quality of coal reserves, as well as those that provided data on wide geographical areas. The annotations were selected and written in late 1977 and early 1978. An annotation form was developed to provide a consistent presentation and thorough review of the information contained in each source. The form is organized into four categories: (1) the data base, (2) the geologic and physiographic parameters, (3) coal characterization parameters, and (4) map data sources. Each of these categories is further broken down into sub-sections. For example, the section on geologic and physiographic parameters includes tonnage estimates, degree of geologic assurance, geographic boundary, mineability and economic features, and seam characteristics. The section on coal characterization parameters consists of the coal quality basis, coal quality data, analytical tests, and physical and chemical properties. In addition to the type of information in each document, the methods used to obtain that information are identified. The annotation form presents a description of themore » assumptions and key definitions, as well as a description of the statistical techniques used. The form also notes whether the document was based on recompiled information or on new data. The annotation forms are arranged alphabetically by author under separate headings for each state. This annotated bibliography serves as a good reference on major documents on coal resources in the United States.« less
