Abstract

Detailed geologic investigations in northwestern Illinois led to the recognition of the Plum River Fault Zone, originally defined as a narrow belt of high angle faults trending roughly east-west for approximately 60 miles (97 km) through northwestern Illinois and east-central Iowa (fig. la; Kolata and Buschbach, 1976). The Plum River Fault Zone was named for exposures along the Plum River near Savanna, Illinois, which first revealed the structure. It is the principal element in an east-west trending belt of structural deformation formerly termed the Savanna-Sabula Anticline (Cady, 1920).
