Description

The Carlyle Dome, an irregular, enclosed area of several square miles, was shown on early structure maps of the Herrin Coal Member (Pennsylvanian). Newer mapping demonstrates that no closure exists on the Chesterian Beech Creek ("Barlow") Limestone (ISGS open files) or on deeper horizons in the Carlyle Oil Field. The coal high may be the product of differential compaction over lenticular lower Pennsylvanian sandstones. The name Carlyle Dome should, therefore, be discontinued.
