Book excerpt: Excerpt from Geology and Coal Resources of the Henryetta Mining District, Okmulgee County, Oklahoma The mapped area of the Henryetta mining district includes about 168 square miles in Okmulgee County in the east-central part of Oklahoma. The rocks in this district consist of sandstone, silty shale, and shale, and are divided into the Senora formation and the overlying Calvin sandstone of Pennsylvanian age. Coal occurs in the Senora formation in two minable beds: the Morris bed and the overlying Henryetta bed. The Morris bed averages about 16 inches in thick ness. Mining of this bed has been restricted for the most part to strip mining in the northeastern section of the mapped area, where the strata have a gentle westward dip of about 1 degree. The Henryetta coal bed averages about 25 to 36 inches in thickness and has been mined extensively to the east, west, and south of the north-trending henryetta-schulter anticline, the only important structural feature in the district. Although this anticline is locally faulted, displacements of the faults are small. At present, the large operating coal mines are on the western side of the anticline. The coal in the Henryetta and Morris beds is of high volatile A and B bituminous ranks. Coal from the Henryetta bed was being used in 1952 in blends for the manufacture of coke at the Sheffield steel plant at Houston, Tex.
