recrystallized limestone; limestone is exposed to high temperatures and pressures
weak epidote alteration: non-metamorphic
green, fine grained, weak foliation\cleavage, fine chlorite
low grade metamorphic: greenschist zone
(similar assemblage as propylite alteration)
Pale green, sheen of slatey cleavage fine chlorite\sericite, greenschist slate (sediment or volcanic??)
Weakly foliated\cleaved greenstone, fine chlorite, sericite
Abundance of fine chlorite suggests a more mafic (basaltic?) original composition.
Foliated to lineated chlorite schist. Elongate patches of chlorite\fine biotite? Relict mafic phenocrysts? Light matrix mix of fine chlorite\sericite.
Foliated to lineated chlorite\hornblende\feldspar schist, moderate high temperature-early amphibolite zone?
Biotite\hornblende felspar gneiss. High grade metamorphic zone
Platy-early development of cleavage\foliation, low grade transitional metamorphic
close spaced parallel fracture\cleavage
strong platy fracture cleavage, fine sheen on cleavage surfaces, fine grained sericite\muscovite, low-medium grade metamorphism
Fine grained sericite schist\phyllite. Presence of white mica on cleavage develops early metamorphic foliation
fine rust and thin brown (iron carbonate-ankerite) veinlets of curious note as to origin
Fine white mica develops good foliation and visible mica and small knots of garnet?
light grey; micaceous; 70% muscovite; 20% biotite; 10% staurolite
25% garnet and 20% staurolite (vitreous, brown) as 1-2 cm porphyroblasts; 55% muscovite; recessive; resistant garnet and staurolite produce knobby outcrop
