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. |
