Description
Photo 6: Alternating layers of light gray feldspathic and micaceous quartz-rich granofels (bottom) and slightly rusty weathering sillimanite-rich garnet-mica schist (top) of the Cape Elizabeth Formation (Oce) of the Casco Bay Group. Prior to metamorphism, these were alternating beds of quartz-rich sand and fine-grained mudstone. The abundance of minerals such as muscovite (white mica), garnet, and sillimanite indicate the original sediments in the Cape Elizabeth Formation were more aluminous than those of the Bucksport Formation (Photo 10) which do not contain these aluminous minerals. Route 96, east side of Linekin Bay, Boothbay.
