Because the paleomagnetic data for the Devonian is conflicting, recent efforts to describe the positions of the continents have concentrated on the rock types associated with particular environments.

These logs used in conjunction with a few lithologic logs and gamma-ray profiles of surface sections (Ettensohn and others, 1979) have proven to be a useful tool for long-range stratigraphic studies.

Stratigraphy of the Devonian Chattanooga and Ohio shales and equivalents in the Appalachian basin: an example of long-range subsurface correlation using gamma-ray logs.

The correlations discussed demonstrate the utility of the gamma-ray log for regional, basinwide stratigraphic studies.

Through the use of these logs, suggested correlations based on paleontologic evidence (Hass, 1956) were confirmed and new correlations were established in the Appalachian basin across at least 700 miles.
