Description

Ball (1952) gave the name Sugar Creek Syncline to a shallow northeast-trending depression on a structure map of the Herrin Coal Member (Pennsylvanian). The syncline lay between two subtle anticlinal noses, which Ball called the Burton and Carlinville Anticlines. A new structure map of the Herrin Coal (Nelson 1987b) shows a structural pattern totally different from that mapped by Ball (1952). Although an irregular enclosed depression occurs in the general area on the new map, the Sugar Creek Syncline, as initially defined, does not exist and the name should not be used.
