The lower part of the Wilcox Group of northwest Louisiana contains shallow (<500 ft), coal deposits that are mined for use in mine-mouth electric power generating plants. The coal deposits, which are lignite A in rank, occur on the eastern part of the Sabine Uplift. The Louisiana Sabine resource assessment area includes parts of four parishes: De Soto, Red River, Natchitoches and Sabine. The assessment area is roughly 60 miles long and 15 miles wide and generally extends across the east central part of the Sabine Uplift in northwest Louisiana. More than 950 stratigraphic records from rotary and core drill holes were used to assess the resources of the Louisiana Sabine assessment area. A total of 1.1 billion short tons of coal with less than 500 ft of overburden were identified in this assessment of the Chemard Lake (Naborton No. 2) coal zone. Maps of the Chemard Lake (Naborton No. 2) coal zone were constructed to show the overburden, structure contour at the top of the coal zone, and cumulative coal-zone thickness. The purpose of the present report is to provide a preliminary release of data for the Louisiana Sabine resource assessment block in advance of publication of the Gulf Coast regional assessment of coal resources, which is planned for a later date.
