| Basis for focus area |
Virginia: Extent of Newark Group in exposed basins; part of the Central Atlantic Magma Province (CAMP event). North Carolina: Mesozoic basins part of the Central Atlantic Magma Province (CAMP event). Buffered area where deposits have been documented. |

| Geologic maps |
Virginia Division of Mineral Resources (1993), scale 1:500,000; Herz and Force (1987), scale 1:24,000; Carter (2008a, b), scale 1:24,000; Leavy and others (1983), scale 1:125,000. |
| Geophysical data |
Inadequate aeromagnetic and aeroradiometric data: Rank 3-5 aeromagnetic and aeroradiometric surveys. |
| Favorable rocks and structures |
Exposed basins of the Newark Supergroup in Virginia and North Carolina. |
| Deposits |
None. |
| Evidence from mineral occurrences |
Potential from mineral system/deposit type. |
| Geochemical evidence |
Unknown. |
| Geophysical evidence |
Unknown. |
| Evidence from other sources |
Unknown. |
| Comments |
Broadly permissive for large igneous province conduit-type Ni-Cu-PGE mineralization and stratiform PGE enrichment (Skaergaard-type stratiform mineralization). |
| Cover thickness and description |
Covered, but possibly less than 100 m. |

| New data needs |
Geophysical data. |
| Geologic mapping and modeling needs |
Geologic mapping could be improved. |
| Geophysical survey and modeling needs |
High resolution aeromagnetic and aeroradiometric coverage. Aeromagnetic data expected to image mafic rocks and associated structures, radiometric data can help with geologic mapping in vegetated terrane; alteration may be imaged. Electromagnetic methods may help image sulfides. |
| Digital elevation data needs |
Lidar adequate. |
