Description

J. Weller and Bell (1936), who mapped a structure they called the Xenia Dome in the east-central part of T3N, R5E, based this mapping on outcrop studies of the Omega Limestone (upper Pennsylvanian) Member of the Mattoon Formation. Easton (1944) showed the Paine Dome in Sections 4, 5, 8, and 9, T2N, R5E, as mapped from well data on the Ste. Genevieve Limestone. Lowenstam (1951) substituted the name Xenia Dome for Paine Dome and further defined it on the basis of subsurface data on the Herrin Coal Member (Pennsylvanian). The current map of the Beech Creek ("Barlow") Limestone (ISGS open files) shows a small dome very similar to that mapped on the coal by Lowenstam. It is elongated east to west and has closure of less than 20 feet (6 m). The Xenia Oil Field, which produces from the Mississippian Aux Vases Sandstone, Carper sand (Borden), and Devonian limestone, is developed on this dome. No dome or anticline exists in the area where J. Weller and Bell (1936) originally defined the Xenia Dome.
