Figure 22. Wildly contorted quartzite and schist layers in the Mosquito Harbor Formation of the Benner Hill sequence at Marshall Point, Port Clyde. The complicated layering and folding in the thin, light-colored quartzite layers is the result of several events. Some folds may be soft-sediment slumps. The foliation is an early metamorphic feature. Most of the folds, shear zones, and migmatite probably accompanied the intrusion of nearby igneous rocks. (Photo 7 of Bath map sheet - pdf format.)
