STRUCTURAL DATA

Layering:
Layering type Strike Dip top Direction
metamorphic layering 126 75

Planar Structures:
Structure type Strike Dip Separation
cataclastic foliation 61 79

PETROLOGIC DATA

Rock Number: 1

Rock Type: multi-component schlieric gneiss

Field Description:

-grey BO TNLT is the dominant phase and over large areas of the outcrop is homo-equi with patches of deformed schlieren and younger intrusions
-the layering direction seems to correspond to the attitude of the Batholith margins and is overprinted by the late shear direction with attendant disharmonic folding
-the TL bearing PGMT seem to be restricted to the 050 foliation direction
-this suggests that the Boron metasomatism is related to a batholith at depth
-possibly centered west of town and feeding into the system via the late shear directions
