Title: Geophysical Evidence for Deep Basin in Western Kentucky

Author(s): R. K. Soderberg (2), G. R. Keller (3)


The Rough Creek fault zone is a major element of the 38th Parallel lineament in western Kentucky and southern Illinois near the head of the Mississippi embayment. Gravity, magnetic, and subsurface data suggest that this fault zone marks the northern boundary of a large graben in the Precambrian basement for which we propose the name Rough Creek graben. This graben is a major structural feature which probably formed initially in late Precambrian to early Paleozoic time and has been reactivated (perhaps several times) during the late Paleozoic and possibly the Mesozoic. The graben is as much as 5.5 km deep and the large volume of deeply buried sediments favors further exploration.
