Description
Treworgy (1981) listed the "Russellville structure" in her table of significant unnamed structures. It was named for the Russellville Gas Field and it appears variously as a dome, an anticline, and an anticlinal nose at different structural levels. The structure appears as an elongated dome or anticline and has an axis trending slightly west of north on the Springfield and Herrin Coal Members (Potter 1956). Potter indicated about 50 feet (15 m) of closure on the Herrin Coal. A south-plunging nose with no closure appears on maps of the Beech Creek ("Barlow") Limestone (fig. 19; ISGS open files). Structure maps of the Ste. Genevieve Limestone show a nearly circular dome (Bristol and Howard 1976, Howard, unpublished mapping). On the New Albany Group (Stevenson et al. 1981) and Galena Group (Bristol and Buschbach 1973) the Russellville structure is best described as a terrace. Control points are few, however, on these deeper units. Production in the Russellville Gas Field comes from Pennsylvanian sandstones. The structure is named Russellville Dome.
