GEOLOGIC SKETCH OF THE PROPOSED NORTHEAST CORRIDOR HIGH-SPEED GROUND TRANSPORT SYSTEM

From a geologic viewpoint, it can be concluded that the rocks of the Crystalline terrain are most suited for underground or surface construction, followed by the rocks of the Triassic terrain. Underground and surface construction in the Appalachian terrain can be recommended with limitation; extensive tunneling in sediments of the Coastal Plain terrain is not recommended because of difficulty of tunneling, but can be effected in underlying crystalline rocks. Subsurface and surface geologic mapping utilizing drilling and geophysical methods is strongly urged before a final route selection is made. Highly detailed engineering geologic studies will be required of the actual route selected before design and construction can begin; feasibility studies and preliminary route selection will require extensive compilation of existing geologic data and mapping at adequate scales.
