Tillotson Peak Structural Complex

Mafic schist and amphibolite unit. Dark-bluish-gray, fine- to medium-grained, massive to foliated blueschist composed of amphibole (glaucophane, barroisite, and actinolite), epidote, garnet, chlorite with minor magnetite, pyrite, and apatite. Quartz and garnet coticule occur locally. Eclogite occurs locally, delimited by green, medium-grained layers and pods of garnet, omphacite, glaucophane, epidote, quartz, albite, and white mica. Rocks of the Early to Late Taconic Accreted Terrane of the Rowe-Hawley Zone. Eastern allochthonous sequence, oceanic and accretionary realm, ultramafic inclusions, volcanic-arc intrusives, and volcanic rocks.
