A Potential Long-lived Upper Cretaceous Paleodrainage System In The U.s. Southwestern Georgia-southeastern Alabama Region

<p>The Gulf Coastal Plain unconformity separates crystalline basement of the Appalachian core from sedimentary units of the Coastal Plain. In the Columbus, Georgia region, basement rocks of the Uchee terrane are typically overlain by sands and gravels of the Tuscaloosa Formation. Sediments within the Tuscaloosa Formation indicate partial derivation from gneiss of the Columbus Metamorphic Complex, the nearby Pine Mountain belt and potentially rocks of Inner Piedmont-eastern Blue Ridge terranes. Mapping along the Coastal Plain unconformity near the Lower Chattahoochee River Valley indicates the presence of one or more large paleovalleys in the Upper Cretaceous sub-Coastal Plain surface that occupy a similar position to a paleodrainage system identified in the overlying Eutaw Formation. Characteristics ofthe Eutaw Formation indicate recycling of Tuscaloosa sediments in addition to crystalline basement sources. Collectively, these data indicate the possibility of a long-lived drainage system in the vicinity of the modern Lower Chattahoochee River Valley.</p>
