Description
The name Irvington Anticline is proposed for an anticline near the village of Irvington in northeastern Washington County. The Irvington Anticline lies on the upper limb of the Du Quoin Monocline and south of the Centralia Anticline; it strikes northwest, en echelon with the Centralia Anticline (fig. 31). The enclosed area of the Irvington Anticline, as mapped on the Beech Creek ("Barlow") Limestone (ISGS open files), is about 3 miles (5 km) long and as much as 1 mile (l.6 km) wide. The fold plunges gently at both ends so that the total length is 5 to 6 miles (8-10 km). Closure on the Beech Creek is approximately 40 feet (12 m). The Irvington Oil Field, developed on the anticline, has yielded 10.7 million barrels of oil to date from the Mississippian Cypress and Yankeetown ("Benoist") Sandstones, Devonian Clear Creek Chert, and Ordovician Galena Group (Trenton).
