Description

Photo 4: Medium- and coarse-grained granite within weakly layered migmatitic gneiss. On the left side of the image are smaller asymmetric dextral sigmoidal lenses of granite typical of the sheared unit of the Passagassawakeag Gneiss (DOpgs). Lighter colored flecks are smaller grains of feldspar or feldspar and quartz. The granite is interpreted as in situ accumulations of melt. The dominant minerals in the granite are quartz, microcline, and plagioclase. The darker host areas are composed of biotite, quartz, and feldspar ± sillimanite. Garnet is generally not present. Photo approximately 800 feet south of the Brooks East quadrangle, in the Belfast quadrangle near Route 131.
