| Basis for focus area |
Buffered point for pegmatite localities in Amelia County, Virginia (Rutherford No. 3 pegmatite, Rutherford No. 2 pegmatite, Rutherford No. 1 pegmatite). |
| Identified resources |
Historical production of feldspar, gemstones, high purity quartz, and mica. |
| Production |
Unknown. |
| Status |
Past mining. |
| Estimated resources |
Unknown, but considered small deposits. |
| Geologic maps |
Virginia Division of Mineral Resources (1993), scale 1:500,000. |
| Geophysical data |
Inadequate aeromagnetic and aeroradiometric data: aeromagnetic data Rank 4; aeroradiometric Rank 5. |
| Favorable rocks and structures |
Pegmatitic deposits. |
| Deposits |
Rutherford No. 3 (MRDS dep_id: 10252355), Morefield mine (MRDS dep_id: 10084287). |

MRDS. |
| Geochemical evidence |
Some elevated Lu in vicinity. |
| Geophysical evidence |

| New data needs |
Geologic mapping. |
| Geologic mapping and modeling needs |
Geologic mapping of pegmatites and surrounding country rocks. |
| Geophysical survey and modeling needs |
High resolution aeromagnetic and aeroradiometric coverage to help with framework geology. Aeromagnetic data may image mafic rocks, associated structures, and possibly alteration zones. Radiometric data can help with geologic mapping in vegetated terrane. |
| Digital elevation data needs |
Lidar complete. |
