GUID (UUID V4):

The Mississippi Embayment is interpreted here as a large Mesozoic sag basin in southernmost Illinois, western Kentucky, southeastern Missouri, western Tennessee, northwestern Arkansas, and northern Mississippi. This structural and depositional feature rests unconformably above the inverted Reelfoot Rift Basin and the Black Warrior and Arkoma foreland basins and was probably controlled by reactivation of the rift boundary faults and cross rift inversion structures (Pascola and Blytheville Arches).
