cataclastic foliation 265 68

PETROLOGIC DATA

Rock Number: 1

Rock Type: granodiorite
Descriptors:
porphyritic
biotite

Field Description:

-quartz 20 to 25 %
-light grey weathering with medium grey glassy fresh surface
-weakly foliated with 3 to 5% phenocrysts or snow white KF.
-probably GRDR verging on TNLT
-fabric is pervasive with local zones of moderate shearing
-outcrop is cut by numerous coarse quartz-rich red potassic pegmatites
-do not appear to be assoc. with peristerite
-dike form is irregular anastomosing
-bears some resemblance to CWB TNLT but generally more homogeneous lacking schlieric nature
