Abstract: Oklahoma Coal Database


Since 1984, the Oklahoma Geological Survey (OGS) has been developing a computerized GIS-based (geographic information system) database of information (location, quantity, and quality) on Oklahoma's coal resources, as part of the National Coal Resources Data System (NCRDS). The NCRDS, initiated in 1975, is a cooperative program of the U.S. Geological Survey and state geological surveys of coal-producing states.

Geologists of the OGS collected stratigraphic and analytical data from every available source, including field investigations (mine and outcrop), coal-mining companies, State and Federal agencies, well drillers, the OGS drilling program, individuals, and literature search. The database presently includes data from 12 counties (Craig, Creek, Mayes, McIntosh, Muskogee, Nowata, Okfuskee, Okmulgee, Rogers, Tulsa, Wagoner, and Washington) in the northeast Oklahoma shelf area.

Stratigraphic header and data tables contain 20,775 records of stratigraphic and geologic information from 4,457 locations.

Analytical header and data tables contain location, stratigraphic and geologic information, determined rank, and analytical (chemical and petrographic) data of 545 samples.

A production table lists Oklahoma coal production by county, percentage surface mined, and value from 1908 to the present.

Examples of queries, maps, and graphs, generated from the data, will be presented.
