PETROLOGIC DATA

Rock Number: 1

Rock Type: multi-component schlieric gneiss
Field Description:

-amounts of old grey to pink megacrystic GRDR (main phase) and young massive grey GRDR
-early cataclasis and igneous layering was 270 degrees direction and is folded in broad z-assymetric folds with a 050 degree axial plane
-short limbs pail on chloritized shears
-extensive intrusion of ping GRNT apilite followed by coarse pink GRNT in 270 degree direction
-only white quartz veins occupy the 050 degree shears
-305 degree direction is a strong joint set that show no shearing but offsets layering 5 to 70 cm
