Field Description:

-grey augen gneiss with 5% old white quartz - poor GRDR lee horn-mobilizate
-extensie augeny, traces of MG, cut by younger, planar, red, MG bearing pegmatites which roughly parallel the foliation and are sheared slightly but have a contact-normal feldspar and BO fabric or orientation which indicates crystallization in a static pressure field
-several small highly flattened amphibolite inclusions
