Clinch River Nuclear Site Early Site Permit Application Part 2, Site Safety Analysis Report Source: Modified from Reference 2.5.1-26 Description of Map Units Gently folded and flat-lying carbonates rocks: indurated limestone and dolomite that has not been strongly deformed. Predominantly found in interior plateaus and lowlands. Dissolution may produce solution, collapse, and cover-collapse sinkholes.
Where carbonates are thick and extensive, cave systems may be long and complex.
Where thin and interbedded with non-carbonates, caves are small and short.
Geometry of cave passage patterns often shows stratigraphic and bedding-plane control often resulting in branchwork caves. (Reference 2.5.1-35)
Folded, faulted carbonate rocks: limestone and dolomite in areas flanking and in orogenic zones. May be intensely folded and faulted, commonly well jointed, commonly with cleavage. These rocks are located in the Valley and Ridge Province on this map and most are Paleozoic in age. Dissolution may produce solution, collapse, and cover-collapse sinkholes. Caves range from small and simple to long and complex systems. Geometry of cave passage patterns tend to show at least some structural control producing network caves. (Reference 2.5.1-35)
Marbles and metalimestones: highly deformed carbonate rocks, usually found in long, thin, linear belts or pods. Mapped areas are often exaggerated as these rocks are usually mapped with associated, non-soluble metamorphic rocks. Dissolution may result in solution, collapse, and cover-collapse sinkholes and small, short caves.

Collision model for the Alleghanian orogeny (From Reference 2.5.1-74).
Red lines and symbols indicate the feature is active in the time interval shown.
A) Initial contact between Gondwana and Laurentia produced step-over basins in New England and deposition in the Appalachian basin.
B) Continued collision resulted in greater clastic input in the foreland, with the development of dextral strike-slip faults in the interior of the orogen.
C) Clockwise rotation of Gondwana begins to dominate the collision, resulting in a more head-on collision in the southern Appalachians.
D) Head-on collision in the southern Appalachians results in thrusting of the Blue Ridge-Piedmont megathrust sheet and foreland fold-thrust belt development.
