Basis for focus area |
Waldoboro series, eastern part of the Brunswick pegmatite field (Wise and Francis 1992). North of Waldoboro series in Appleton, Knox County, Maine. |
Identified resources |
Historical production of feldspar and mica. |
Production |
Unknown. |
Status |
Past mining at Starrett (1930-1933); exploration at the PEG Claims. |
Estimated resources |
Unknown. |
Geologic maps |
Sidle (1991), scale 1:24,000; West (2006), scale 1:24,000; Hussey and Marvinney (2002), scale 1:100,000; Osberg and others (1985), scale 1,500,000. |
Geophysical data |
Inadequate aeromagnetic and aeroradiometric data: Rank 5 aeromagnetic and aeroradiometric data. |
Favorable rocks and structures |
Pegmatite. |
Deposits |
Starrett (Hollis) mine (MRDS dep_id: 10145911), PEG Claims, Appleton deposit. |
Evidence from mineral occurrences |
MRDS; Felch and others (2016). |
Geochemical evidence |
Favorable mineralogy and rock type. |
Geophysical evidence |
Unknown. |
Evidence from other sources |
Unknown. |
Comments |
May be related to the emplacement of the Waldoboro Pluton. Pegmatites outcrop on eastern edge, emplacement may be structurally controlled. |
Cover thickness and description |
Variable limited cover and glacial cover estimated at less than 2-50 m. |

New data needs |
Geologic mapping. |
Geologic mapping and modeling needs |
Detailed mapping of pegmatite bodies, geophysics may not be useful for pegmatites. |
Geophysical survey and modeling needs |
High resolution aeromagnetic and aeroradiometric coverage can assist with framework geology such as structural features and contacts. |
Digital elevation data needs |
Lidar complete. |
