Comments on Geologic Parameters

3 Formation Thickness:

There currently is no published map of Tuscaloosa Group thickness distribution for the Mobile region (Jack Pashin, Alabama Geological Survey, personal communication, April 2000). We used the thickness information from the cross sections of Mancini and others (1987) to generate the lower Tuscaloosa Group thickness-distribution map for the GIS. We also digitized unpublished data supplied by Jack Pashin (Alabama Geological Survey, personal communication, 2000) and gridded the result (c3tuscaloosag).
