Description
As mapped on top of the Ironton-Galesville Sandstone (Cambrian), the Shanghai Dome is an oval structure about 2 miles (3 km) in diameter and has about 95 feet (28 m) of closure. On younger strata the closure decreases, suggesting that some structural movement took place before Champlainian (Middle Ordovician) time. A gas storage field has been developed on the dome in the Ironton-Galesville Sandstone.
