Includes bibliographical references (p. 80-82). “The commercially significant subbituminous coal resources within the lower Horseshoe Canyon Formation near Sheerness, Alberta, were examined in the context of Canada's National Coal Inventory program. A correlation framework comprised of four coal zones and two marker horizons was established using data from 1228 borehole sites, with an aggregate drilled penetration in excess of 22,000 m. This framework forms the basis of the geologic model which defines geometries and distributions of coal seams. A verified computer-processable database was produced and computer-assisted techniques were applied to all phases of the study. The database and resource estimates can be readily updated and revised. In addition to providing the framework for estimating resources quantities, the geologic model can also be used to assist the planning of efficient resource exploitation and to predict geological conditions in laterally equivalent strata where less substantive data are available"--Abstract, p. 1. gccst Coal gccst Geology Canada.
