The Gulf Trough is southwestern Georgia is known to affect the dips and thickness of units down through 

 the upper Eocene. It would be interesting to know more about this structure at depth and what caused it. 

 The surface formations may have been downwarped affecting the deeper formations or local differential 

 compaction may have caused the trough with no structure reflected in the deeper sedimentary units. 



In the northeastern part of the Georgia Coastal Plain, the Cretaceous deposits have been lumped to- 

 gether as Tuscaloosa Formation (Herrick, 1961) and as "rocks of Tuscaloosa to Providence age undif- 

 ferentiated" (Eargle, 1955). To correlate those rocks with their equivalents to the west, the study of spores 

 should be undertaken. This seems to be the only method currently available that can permit such a cor- 

 relation to be made.
