The fault zone is composed of at least eight en echelon faults and has been mapped for more than 24 km (15 mi). Geologic mapping and drilling indicate that the fault zone has had as much as 30 m (100 ft) of apparent vertical offset since the deposition of the Late Cretaceous to middle Tertiary Coastal Plain sedimentary rocks, and ∼ 23 km (14 mi) of apparent left-lateral offset since the metamorphism of the Paleozoic crystalline rocks. The configuration of the inner margin of the Coastal Plain northeast of Augusta suggests that the Belair fault zone is much longer than presently mapped and that Coastal Plain rocks were possibly involved in the transcurrent displacement.
