Introduction. The tectonic landscape of the Carboniferous was complex, with orogenesis occurring along much of the Laurentian margin. The Appalachian orogenic series culminated in the Alleghanian orogeny on the eastern margin of Laurentia, and the southern margin of the continent saw the east-to-west closure of the Rheic Ocean and deformation tied to the Ouachita-Marathon orogeny (Hatcher ...Mississippian) for exposures along the stream of that name heading in Newton County, Kansas, and flowing westward into the Spring River in Cherokee County, Kansas (Smith and Siebenthal 1907).
