Oxford pegmatite field?

Coordinates are general for Bemis Stream.

The origins of the Bemis Stream granite pegmatite are unknown. In Western Maine, the granitic pegmatites are believed to have been derived by partial melting of muscovite-bearing pelitic rocks [London, 2008; Simmons, W., Foord, E., Falster, A., and King, V., 1995]. The Sebago Batholith (~294 my BP) and the much older Mooselookmeguntic Pluton (~370 my BP) are candidates for the heat source leading to partial melting and generation of pegmatite-forming fluids in this area. However, there is a proximity factor favoring the older pluton. An even older thermal event (~404 my BP) may be responsible for the necessary heat. Although there are granite/granodiorite-hosted granite pegmatites in Western Maine, most of the Western Maine granite pegmatites are probably not derived from plutonic source fluids, but from the thermal aureole associated with plutons. Studies are currently underway to further characterize the origins.
