Description

Workman (1940) observed that several oil-producing domes and anticlines, extending from Macoupin County on the northwest to southern Marion County on the southeast, are arranged more or less in a line. This observation led him to postulate the existence in this area of a fold belt or anticlinorium comparable to the La Salle. Subsequent deep drilling and structural mapping (Bristol and Buschbach 1973, Bristol and Howard 1976, Stevenson et al. 1981) demonstrated that the structures noted by Workman are unrelated and do not constitute a fold belt. The term Carlinville-Centralia Anticlinal Belt has dropped out of usage.
