Metamorphic mineral assemblages from both sides of the study are interpreted to be the result of a prograde reaction sequence.

To the north, the preserved assemblage began as Chl, Ms, Ill, and Mt (chlorite grade), and progressed to Grt, St, and Bt, (garnet and staurolite grade). To the south, the preserved assemblage began as Bt, Ms, Ill (biotite grade), progressed to contain Grt, St, Bt, (garnet and staurolite grade), and concluded with biotite and kyanite. These two assemblages are similar, but appear to be offset from north to south.

Calculation of peak metamorphic conditions on the assemblage of garnet, plagioclase, kyanite, muscovite, and biotite using the TWQ thermodynamic database and other calibrated thermometers and barometer, has provided temperatures and pressures also differ north to south.

To the north conditions were ~580šC and 4.5 kb, and to the south were 595šC, and 5.7 kb. This >1kb difference in pressure corresponds to an approximate 3 km offset in rocks between the shallower northern rocks and deeper southern rocks of the study area.
