| Basis for focus area |
Archean and younger granites suspected to have significant potential for LCT pegmatites, based on their setting (for example, Selway and others 2005). |
| Identified resources |
None known. |
| Production |
No known production. |
| Status |
Unknown. |
| Estimated resources |
No data. |
| Geologic maps |
Cannon and Ottke (1999), compilation scale 1:100,000. |
| Geophysical data |
Mostly (>75%) inadequate aeromagnetic coverage, inadequate aeroradiometric data. |
| Favorable rocks and structures |
Archean granites with some known pegmatites, also some Paleoproterozoic granites. |
| Deposits |
No data. |
| Evidence from mineral occurrences |
No data. |
| Geochemical evidence |
No data. |
| Geophysical evidence |
Weakly magnetized granites. |
| Evidence from other sources |
Favorable comparisons to areas with known potential (for example, Selway and others, 2005). |
| Cover thickness and description |
Glacial cover (<50 m). |

| New data needs |
New mapping, high resolution geophysics. |
| Geologic mapping and modeling needs |
More detailed mapping, to the extent allowed by glacial cover. |
| Geophysical survey and modeling needs |
Rank 1 aeromagnetic data, also radiometric data. |
| Digital elevation data needs |
Lidar adequate over part of focus area, inadequate over others. |
