Description

Newton (1941) postulated the Sigel Anticline on the basis of a single control point in Section 26, T9N, R6E. Subsequent mapping based on dozens of test holes drilled since 1941 demonstrates that no dome or anticline exists at the point indicated by Newton. No structural highs are apparent on Du Bois' (1951) maps of four Pennsylvanian units in this area. The nearest areas of closure indicated on current Beech Creek ("Barlow") Limestone maps (ISGS open files) are small domes associated with the Teutopolis and Lillyville North Oil Fields, which are about 2 miles (3 km) south and 3 miles (5 km) east of Newton's Sigel Anticline. The dome at Lillyville North is due to draping of strata over a Silurian reef. The origin of the dome in the Teutopolis Field is uncertain; no wells there have reached Silurian rocks.
