This book examines the geology of southernmost Illinois, an area where sedimentary strata obscure older rocks and contribute to the geophysical anomalies of the Mississippi River Valley. The author draws on surface and subsurface data to investigate recurrent faulting and the displacement of pre-Cretaceous sediments. This study suggests the surface upon which the Cretaceous was deposited was of comparatively low relief and that the present relief is largely the result of later movements of the faulted blocks of Paleozoic rocks underlying the area. The author concludes that some of the anomalous levels of the âLafayetteâ Gravel may be the result of faulting, and some of the broader flexures may be the result of warping, in an area that shows evidence of recurrent seismic activity.
