Cooling-age contours derived from 40Ar/39Ar ages hornblende, muscovite, biotite granitic plutons their country rocks show a regional pattern younging toward southeast. cooling-age gradient, along with distribution normal faults, discontinuities metamorphic grade, rifting South Georgia basin crystalline between Brevard fault Coastal Plain unconformity were exhumed as lower plate an detachment system. The Suwannee Charleston terranes likely preserve part upper plate. These features represent postorogenic probably extensive system Permian–Middle Triassic. episode extension may have played crucial role thinning continental crust its current thickness was first stage eventually Pangea formation Atlantic Ocean.
