Abstract
This report is a brief summary of a series of papers presented at the North-Central Geological Society of America meeting in Ames, Iowa, 1981 (Bunker, et al., 1981; Bunker, 1981a,b). It is an update of information from the files of the Iowa Geological Survey that has accumulated since the original work summarizing the regional structural development of the Forest City Basin area (Lee, 1939, 1943, 1946, 1948, 1956; Anderson and Wells, 1968). The present day structural configuration of southwestern Iowa is the result of several periods of discordant structural movements. These movements have warped the originally flat lying formations in different directions and at different times during the Phanerozoic. Anderson (p.40 ) summarizes the interpreted structural development of the Late Precambrian Keweenawan rift system, which passes through Iowa.
