Structure type | Strike | Dip | Separation
cataclastic foliation | 264 | 63 |

-major mylonite zone 10 m thick
-rock reduced to schlieric mylonite gneiss since last station the felsic component decreased into a section dominantly HB greywackes with epidote pods
-at this location intense shearing mylonitization and veining of pseudotachylite has obliterated whatever field relations existed

PETROLOGIC DATA

Rock Number: 1

Rock Type:
Field Description:

-there appears to be several unrelated fault slices, some containing arkosic material, others contain greywacke only
-the centre of the mylonite zone is a buff coloured fine grained mylonite gneiss, containing numerous inclusions of greywacke
-it appears to be an intrusive layer of granitic material, and evasive into the fault
