Cincinnati Arch Geology

De spite the great age of these formations exposed in the cincinnati. The axis of the cincinnati arch extends southward from ohio to tennessee. One of the older geological formations of the earth has been bulged up into the broad uplift known to geologists everywhere as the cin cinnati arch and has been exposed by subsequent erosion.

The cincinnati arch is a broad structural uplift between the illinois basin to the west the michigan basin to the northwest and the appalachian basin and black warrior basin to the east and southeast.

Cincinnati arch geology. A veneer of paleozoic sedimentary rocks as much as 5000 ft thick covers the basement rocks. Structural geology cincinnati arch the cincinnati arch is one of several structural highs which determine the distribution of outcrop in the central interior of the united states. It existed as a persistent low lying land area flanked by seas covering a large part of the continent while connected with the ocean. Cincinnati arch geologic anticlinal archlike structure influential during the paleozoic era 542 million to 251 million years ago.

It existed as a positive topographic area during late ordovician through the devonian period which stretched from northern alabama northeastward to the southeastern tip of ontario. Ably the greatest single factor is the geology of this area. The axis passes through central tennessee and kentucky in a north by east direction and splits in northern kentucky with one limb passing on each side of the michigan basin. The cincinnati arch province 066 consists of broad basement involved arches domes and intervening sags and saddles that separate the appalachian and illinois basins.
