Description
Photo 8: A view towards the north-northeast of tight, shallowly plunging, upright folds (f2) in layered granofels of the Bucksport Formation (Sb). Granofels, metamorphosed siltstone or fine-grained sandstone, are hard crystalline rocks with a fine-grained granular texture. In addition to fine-grained quartz and feldspar, the darker colored granofels layers are rich in fine-grained biotite, and the lighter colored layers contain calcium-silicate minerals such as diopside and calcic amphibole. The folds formed during roughly east-west directed crustal shortening associated with the Devonian Acadian orogeny. Cow Island, Bremen.
