Excerpt: ... CALDERWOOD''S NECK SCHISTS. Descr1pt1on And D1str1but1on. The rocks included in this series are dark quartzitic slates, often rusty on the weathered surface, banded schists, quartzose but varying in color and grain, and quite massive quartzites. These rocks occupy the northern half of Caldcrwood''s Neck, with the exception of the narrow part west of Carver''s Cove. Felsitic rocks occur in close proximity to the granite and volcanic rocks and undoubtedly represent contact phases of members of this Calderwood''s Neck series. These are mottled or variegated, the general color being a light green. In the thin section, they are seen to be composed of nearly pure epidote with some zoisite, in the lighter areas, and of green hornblende in the darker. Connected with this larger area is a narrow strip of similar rocks along the western shore of Seal Cove. Here the rocks are somewhat more massive, being both quartzitic and slightly calcareous. Epidote is quite prominent along the bedding planes, giving a banded appearance in many places. Rocks resembling these in general appearance occur elsewhere on Vinal Haven, on the shore of Leadbetter''s Narrows, and on the extreme eastern side of the island near Coombs'' Hill. In the latter occurence the schists are actinolitic in appearance, except where in contact with a granite dike. Here there is a marked bleaching of the schist similar to that observed at several localities in the Calderwood''s Neck area. There are also indications of small masses of these schists within the diabase area''of Barley Hill, and the volcanic area on the western side of Vinal Haven, but these areas are too small to be mapped. On North Haven, the presence of this series is not indicated at any point. Relat1ons. The series in its principal development distinc...
