Layering in amphibolite. North Anguilla Road, Stonington. New London County, Connecticut. May 1963.

Aligned biotite flakes in sill of fine-grained, saccharoidal Hope Valley Alaskite Gneiss in Plainfield Formation. All the biotite flakes are aligned, and foliation described by them passes through the noses of the "folds." The biotite is probably the remnant of an inclusion and the alignment was produced by magmatic flow. 0.48 mile north, 29 degrees west of the outlet of Green Fall Pond, Voluntown. New London County, Connecticut. April 22, 1963.
