Clays of the Central Georgia kaolin belt comprise a significant percentage of commercial grade kaolin produced worldwide. Kaolin lenses occur in terrestrial Coastal Plain sediments in east-central Georgia, in updip sections near the Fall Line. Uniformitarian models of the clay’s origin suggest the following sequence occurring over millions of years: (1) kaolinite minerals slowly formed as weathering products of updip igneous and metamorphic rocks of the Piedmont and Appalachian provinces, (2) kaolinite was transported by rivers to the ancient coastline, and (3) extensive, slow post-depositional changes resulted in nearly pure kaolin bodies. However, present theories are troubled by a number of inconsistencies and the diluvial paradigm may prove more fruitful for understanding the occurrence of the clay. Though a diluvial model is not presented, bounding parameters and key questions for such a theory are proposed.
