Information leading to the delineation of this focus area

Basis for focus area Quetico subprovince known to have significant LCT pegmatite potential, based on what's known from its extent in Ontario (for example, Selway and others, 2005).
Identified resources None known.
Production No known production.
Status Unknown.
Estimated resources No data.
Geologic maps Jirsa and others (2012), scale 1:500,000.
Geophysical data Inadequate aeromagnetic and aeroradiometric coverage.
Favorable rocks and structures Metasedimentary rocks and granites of the Quetico subprovince.
Deposits No data.
Evidence from mineral occurrences No data.
Geochemical evidence No data.
Geophysical evidence No data.
Evidence from other sources Favorable terrane in Ontario.
Cover thickness and description None to thin glacial cover in eastern part of state, increasing to ~40m +/- 40 m in western part of state.
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 eastern half of area; inadequate over western half.
