The 2.1 Ga old FB Formation of the Franceville Series, southeastern Gabon, contains one of the greatest accumulations of organic carbon of its age. The weakly metamorphosed, dominantly pelitic, FB Formation ranges in thickness from 400 to 1000 m, covers over 35,000 km 2, and consists of about 80% ma...
