Granite pegmatite. Plumbago Mt. - Oxford pegmatite field. (At base of summit ridge to north of Dunton Quarry on Hall's Ridge.) Opened about 1952 for beryl. Possibly the largest beryl producer in the State, probably exceeding the Bumpus Quarry although records are probably inaccurate due to the secrecy associated with beryl production in general. Land currently owned by Plumbago Timber and Quarries LLC which permitted use of new mineral discovery information to appear on mindat.

Devonian - Silurian Madrid Formation
Probably named for Madrid, ME. Consists of calcareous quartzite with lime-silicate minerals in middle-grade metamorphic zones. Contains minor amounts of argillaceous rocks and calcareous beds. Sulfides absent or inconspicuous. Quartzite grades upward into Dyer Hill member (new). Age is younger than Parmachenee formation (new). (ME031) Unit description from USGS GEOLEX website (ME078). AA - Low rank amphibolite facies; Protolith M - Calcareous sandstone; interbedded sandstone and impure limestone To avoid digital confusion with Dsm, the map symbol for this unit (DSm) has been changed to DSmd in this file and on the digital map.
