---|---|---|---|
schistosity | 239 | 77 |
Type | Plunge | Azimuth |
---|---|---|
rodding | 69 | 333 |
-cataclasis much less pronounced, largely restricted to greywacke inclusions
-granitic still retains good euhedral phenocryst form
PETROLOGIC DATA
Rock Number: 1
-coarse white seriate GRNT containing phenocrysts ranging from 4 mm to 5 cm in size
-minor traces of molybolinite
-numerous schlieren probably derived from pelitic gneiss
-70% of outcrop is granite
-numerous 1 to 5 mm rusty patches, occasionally with white sulfide in core
-some minor patchy, almost miarobitic development of pegmatite
Mineral | Abundance (%) |

Rock Number: 2
-30% highly deformed and boudinaged inclusions of Burntwood style greywacke
-summits containing CLCC inclusions are dominant
-pelitic layers largely reduced to schlieren
-thin biotite selvages form along contact of granites
-pelitic inclusions largely consist of felted muscovite and sillmanite
