STRUCTURAL DATA
Structure type | Strike | Dip | Separation |
---|---|---|---|
schistosity | 2 | 20 |
-2 photos (unlabelled) from boat showing seds at low angle climbing over granite margin
PETROLOGIC DATA
Rock Number: 1
-extensivly altered and recrystallized by intrusion of the main body of CWB.
-little can be recognized over than mafic HB rich character; suggesting volcanic origin
-foliation and layering seem to correspond to contact with gray granite to the west
-once again suggesting the supracrustals are drapped over a dome margin
Rock Number: 2
-Granite contains minor amounts of granite adjacent to contact of supracrustals but otherwise resembles main phase of CWB complex
-Only exception to this is fact it has undergone hardly any shearing or tectonic disruption.
-fine grain chill(?)
