Summary:
Principal, and probably oldest, unit of the Kiokee belt outlined by Crickmay (1952: Georgia Geologic Survey Bull. 58) is a granitic biotite gneiss. Alternating biotite-rich and quartzo-feldspathic layers form pronounced color banding. Kiokee gneisses, with associated granitic and ultrabasic intrusives, underlie most of Columbia Co. from Keg Creek southward to Richmond Co. In extreme southeast corner, Kiokee rocks are in contact with Little River Series. Southward both the Kiokee and Little River Series are overlapped by Tuscaloosa sediments. The Kiokee gneisses extend westward from Columbia Co., across central McDuffie, and into central Warren Co. with little change.
