STRUCTURAL DATA
Structure type | Strike | Dip | Separation |
---|---|---|---|
cataclastic foliation | 56 | 32 | |
fault | 241 | 51 |
Fault is a 1.5 metre ultramylonite zone
PETROLOGIC DATA
Rock Number: 1
-Resembles the previous hornblende granodiorite but with very little quartz and high mafic content.
-Numerous inclusions including mafic supracrustals and leucocratic granodiorite to tonalite.
-Extreme cataclasis due to fault has agmatized everything in a homogeneous grey cataclasite matrix that looks to be largly derived from quartz diorite
