Description
Photo 2: Google Earth view of Crow Island, South Bristol, a location not visited by either of the map authors, but a location interpreted to be underlain by interlayered biotite and calc-silicate granofels of the Bucksport Formation (Sb). The thinly spaced systematic fracturing and color banding oriented ~010° is interpreted to represent the strike of compositional layering. The dip angle or dip direction cannot be estimated from this image. Note the presence of sills (parallel to layering) and dikes (oblique to layering) of light colored granitic rock intruding the gray metamorphic rocks.
