Abstract

Upper Cretaceous marine sediments of western and eastern Georgia were studied using planktonic foraminiferal biostratigraphy across seven stratigraphic sections spanning the Uppr Albian–Lower Santonian interval. Ten biochronological units were established. Their succession was analyzed in relation to lithological changes, OAE2, post-anoxic recovery, and Cretaceous Oceanic Red Beds (CORBs), providing a basis for regional biostratigraphic correlation.
