Geology and strippable federal coal resources in the south half of the Dunn Center lignite field, Dunn County, North Dakota
During the summer of 1975, Natural Gas Pipeline Company of America (NGPL), with the permission of the Bureau of Land Management, drilled 157 coal test holes into federally owned coal in the south half of the Dunn Center lignite field. This report presents the results and evaluations derived from that drilling. The Dunn Center lignite field lies entirely within Dunn County, North Dakota. Exposures of bedrock within the study area are of the Sentinel Butte Member of the Fort Union Formation (Paleocene). This member contains the four coal beds discussed in detail in this report: from deepest to shallowest, the Dunn Center, A, B, and C. These beds are, all or in part, shallow enough (within 150 ft; 45.7 m of the surface), thick enough (at least 30 in.; 76 cm), and of sufficient lateral extent to be economically extracted using conventional strip-mining methods.
