| - Found near the base of the Spruce
Pine Thrust Sheet - Formed during subduction during the
Taconic Orogeny and incorporated into the accretionary
wedge that is now part of the Ashe Metamorphic Suite
- Contains garnet, omphacite, rutile, pyroxene
and quartz with garnet inclusions of
clinozoisite, titanite, rutile and quartz (Hibbard et.
al., 2001, Stewart et. al., 1997) -
Both prograde and retrograde metamorphism found at
this outcrop - Age estimate of peak eclogite facies
metamorphism is approx. 460Ma with peak minimum
pressures and temperatures of 13-16 kbar at 600-800 C
