STRUCTURAL DATA

Planar Structures:
Structure type | Strike | Dip | Separation
schistosity | 342 | 45 |

Rock Number | Type | Width (m) | Strike | Dip
0 | pegmatite | 0.00 | 295 | 52

PETROLOGIC DATA

Rock Number: 1

Rock Type: granodiorite
Descriptors:
augened
biotite
Field Description:

-since last station gradual increase in mafics and in grain size
-also, slows increase in inclusions, now recognizable, at least as supracrustals
-gradual increase in number and size of pegmatites that appear as swarm

Rock Number: 2

Rock Type: pegmatite
Field Description:

-swarm of parallel pegs, KF rich and quartz poor with black mafic clots that appear to be BO and CL(?)
-SEE SAMPLE
-there is some shearing on dike margins and movement between dikes in counting rock (ie-foliation in GRDR is rotated slightly) so dikes are probably occupying an en echelon fault site.

Minerals of Note
