Description

The name York Dome was given by Mylius (1927) to slight doming on the "Siggins sand" (Carbondale Formation, Pennsylvanian) in the York Oil Field. Clegg did not mention a York Dome; his structure maps of Pennsylvanian coals indicate no closure in the York Oil Field. The field lies on the upper limb of the west-facing Charleston Monocline, which is part of the La Salle Anticlinorium. Because no dome is evident, the name York Dome should not be used.
