Description

Photo 2: Dark gray, very coarse-grained amphibolite in the Nehumkeag Pond Formation (Onpa). The rock is composed primarily of the mineral hornblende and light can be seen reflecting off cleavage surfaces in this mineral. These rocks are interpreted to represent metamorphosed mafic igneous rocks. The light-colored rock in the upper right corner of the photo is a younger cross-cutting pegmatite dike of granitic composition. Shoreline exposure approximately 2000 feet southwest of Brewers Point in South Freeport.
