| 2 fabrics:S1 is the phyllitic
foliation, which is affected by the crenulation cleavage (S1 is folded and
crosscut by the pressure solution planes). Both fabrics are crosscut by
auriferous veins |
S1 fabric is crosscut by the
crenulation cleavage defined by the pressure solution planes with residual
carbonaceous matter. |

composed of carbonates, pyrite, quartz, and albite |
a body of hydrotheraml breccia was
emplaced along S1. Note the rotation of individual clasts in the breccia. |

a fragment of the top-left corner of the above image. Stage 4 layered
hydrothermal rocks form elongated bodies (1-5X5-150m). the layering
is defined by different proportions between light- and dark-colored
mineral and fine phyllitic clasts in separate layers. These layers
then were folded into gentle to very tight and intense folds. Note
the typical "ductile" appearance of the deformation style in
this specimen. The surrounding rocks do not exhibit such feature,
being deformed in a "brittle" manner, i.e. veins, stockwork and
hydrotheraml breccias. Such different style of deformation may be explained
by different mineral composition, hence different rheologies of these
rocks and the surrounding phyllites. The composition was most intensely
changed along fluid channelways, to which these rocks are confined.
The presence of fluids would enhance the ductile deformation. |
