STRUCTURAL DATA

Planar Structures:
Structure type | Strike | Dip | Separation
cataclastic foliation | 34 | 59 |

PETROLOGIC DATA

Rock Number: 1

Rock Type: gneiss
Descriptors:
cataclastic
biotite
Field Description:

-quartz=20%
-grey weathering with considerable decrease in vol. of megacrysts
-much closer to a TNLT comp. than previous stations
-still heavily sheared outcrop is cut by numerous BO-bearing pegmatites with abundant magnetite
-these are only slightly affected by shearing
-MV is a significant feature of this intrusive and wasn't noted in previous megacrystic GRDR adn doesn't appear to be restricted to foliation plane and is primary, not alteration
