Park Publication_Date: 2010 Title: WoCQI_v1_meta.txt Description: Abstract: The U.S. Geological Survey (USGS), in conjunction with collaborating geoscientists from agencies outside the United States, developed the World Coal Quality Inventory (WoCQI), a digital compilation focused on the major-, minor-, and trace-element chemistry of coals from around the world. Emphasis was placed on obtaining coal samples from active mines, but samples of opportunity from countries that do not have significant coal production are also represented in the dataset. However, many coals currently being produced were not able to be sampled. For internal consistency, analyses were performed by only two laboratories: the USGS Energy Program Geochemistry Laboratory in Denver, CO and Geochemical Testing, Inc., a commercial laboratory in Somerset, PA. Data are organized in a consistent format in two separate Excel (2003) files, WoCQI_v1.xls and WoCQI_ADD_v1.xls. WoCQI_v1.xls is the primary dataset for the WoCQI. The file, WoCQI_ADD_v1.xls, contains additional coal chemical data that in general do not meet the lab criteria for WoCQI_v1.xls. WoCQI_v1.xls includes information on USGS current analytical method reporting limits and significant digits. Chemical data are sorted alphabetically by country, and the chemical information includes some or all of the following: proximate and ultimate analyses as well as forms of sulfur on an as-received basis, ash fusion temperatures (degrees Fahrenheit, reducing atmosphere), Hardgrove grindability index (HGI), free-swelling index (FSI), apparent specific gravity, major and minor oxide values (on ash), and major-, minor-, and trace-element concentrations on a whole-coal basis. Commercial laboratory analyses follow ASTM standard methods listed below. Data generated by the USGS laboratory also utilize ASTM methods, when possible. Available sample provenance information is also included. Other data may have been generated, such as low-temperature ash, X-ray diffraction data (semi-quantitative mineralogy), and vitrinite reflectance or other petrographic data, but these data are not included in this compilation. Please read the project summary text and also descriptions of individual attributes contained in this metadata file for the Excel files as to: limitations on existing sample information; the chemical basis of the value, including any calculations performed; and analytical method and caveats for using any particular attribute. Purpose: The purpose of the WoCQI is to provide an internally consistent dataset on available coal samples collected from around the world. Foreign collaborators were given sample collection guidelines by their country's respective USGS counterpart plus a list of required descriptive information for samples they submitted, although in some cases this information is lacking. This dataset can be used to identify future research areas, such as investigating factors that may affect technical utilization and environmental impacts from mining or using coal. To do so, a major assumption must be made that the samples analyzed are representative of the coals being mined. Note that both sample availability and adherence to standard collection procedures will vary greatly between countries.
