Description
Abstract
This compilation contains the major-, minor-, and trace-element chemistry and petrography of coals from Bangladesh. Some chemical analyses were performed by the USGS Energy Program Geochemistry Laboratory in Denver, CO. This compilation contains provisional chemistry, reflectance, and maceral composition of coals collected in Bangladesh from studies related to USGS activities with international agencies. Chemical data are sorted alphabetically by country, and the chemical information potentially includes 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. Partially published before at http://pubs.usgs.gov/of/2010/1196/.

Purpose
The purpose is to provide an internally consistent dataset on available coal samples.  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 may vary.
