PETROLOGIC DATA

Rock Number: 1

Rock Type: multi-component schlieric gneiss
Field Description:

-WJC GRDR with numerous schlieren and mafic inclusions 5 % of exposure is dikes or sills of CWB TNLT or GRDR
-majority of inclusions are GBBR HB'dite
-there are layered HB-DI?? volcanic Ampb majority of inclusions
-actually lie with in inclusions of white pegmatitic GRDR
-one inclusion of lyro?? volcanic is definitely folded with an axial planar developed
-this suggest significant deformation of mafic pile before before being included

Rock Number: 2

Rock Type: diabase
Field Description:

-4 m Molson
-central Gr. Sz. 1.5 mm
-good MG
-slight 056 fabric
-second 15 cm around 11 dike
