PETROLOGIC DATA
Rock Number: 1
-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
