Service Description: This dataset was compiled to update the Coal Fields Map of the Conterminous United States OFR 96-92, using new data provided by the USGS Energy Program NCRA assessments. The pdf and shapefiles were updated with the intent to remove outdated economic information that was rendered obsolete due to changes in technology. New
attributes for regional or area names, provinces, and the geologic age of the coal were added as well as in other miscellaneous graphic products for demonstration purposes with other Federal agencies and Congress.

Description: This dataset is a polygon shapefile representing the most recent
update of the coal fields of the conterminous United States. Scale of
data is 1:5,000,000. This publication is based on a USGS paper map
that was a representation of the coal fields and major regions of the
time (Trumbull, 1960). Trumbull's 1960 map was digitized and coal
fields from the Gulf Coast were added to create USGS OFR 96-92, Coal
Fields of the Conterminous United States (Tully, 1996). Tully's
(1996) publication consisted of a map in pdf format that could be
printed, and an ArcInfo coverage of the coal fields, attributed with
rank and potential economic use (minability) of the coal. This new
dataset includes a pdf showing updated coal fields and a shapefile
that contains attributes on coal rank (without regard to outdated
economic standards), province, name, and age. The data used to update
Tully's (1996) digital map was collected from the National Coal
Resource Assessment (NCRA) regional Professional Papers produced by
the USGS and from AAPG Discovery Series 14/Studies in Geology 62, all
of which were conducted by USGS geologists and professional staff. A
small number of field names were added and or updated in the western
states of Washington, Oregon, California, Utah, Colorado and New
Mexico using additional coal resource literature.
