Information leading to the delineation of this focus area

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.
