gneissosity 65 50

PETROLOGIC DATA

Rock Number: 1

Rock Type: gneiss
Descriptors:

Field Description:

-pink and grey laminated gneiss
-mobilized and highly deformed
-late pegmatite injection
-bull quartz pods
-epidote coatings on late shears parallel to main fabric
-compositional variation from light grey psammitic textured layers to coarser pinker magnetite rich more feldspathic arkosic layers with minor hornblende
-some delicate lamination preserved but is generally to mobilized to tell much about the rock type
-probable high grade sed.
