STRUCTURAL DATA

Planar Structures:
Structure type | Strike | Dip | Separation
gneissosity | 41 | 63 |

PETROLOGIC DATA

Rock Number: 1

Rock Type: granodiorite
Descriptors:
augened
biotite
Field Description:

-zone of schollen gneiss approximately 5% of outcrop is highly digested inclusions of amphibolites
-only volcanic and volcaniclastic sediments are observed
-assimilation is almost complete in most inclusions leaving scheiric zones outlining the original form
-layering in the inclusions trends 140 degrees
-compressive deformation is very high, reducing early pegmatites to coarse augen gneiss
-there are several discrete mylonite zones with a feathered anastamosing character
