Information leading to the delineation of this focus area

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).
Authors Benjamin J. Drenth, Klaus Schulz.
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.
