STRUCTURAL DATA

Planar Structures:
Structure type Strike Dip Separation
cataclastic foliation 51 73

PETROLOGIC DATA

Rock Number: 1

Rock Type: multi-component schlieric gneiss

Field Description:

-mixed intrusion and supercrustal complex
-no single phase appears to be dominant
-inclusions include GBBR and diorite of the old mafic complex and assorted types of VOLC clastic rocks
-PGMT is very abundant with several different pages
-the whole thing is moderatly sheared
-inclusion assimilation is quite advanced with many reduced to BO or HB schlieren
-this is probably a mixture of Whiskey Jack GRDR and CWB TNLT
-one medium grained GBBR inclusion was intruded by a gneissic HB TNLT (grain size 1 mm, CI=12)
