massive and foliated types closely associated with one 

 another. 



Locality i. — Half a mile east of the Indian village on 

 Parry island, the shore rock is entirely made up of massive 

 gabbro. The rock consists of purplish plagioclase, fresh 

 augite, and a little red garnet. 



Banded gneiss near Sans Souci, Georgian bay, Ontario. 



Locality 2. — On the peninsula to the east of the 

 deep bay one mile and a half east-northeast of Locality 1 

 the same type of gabbro may be seen, but is here intimately 

 associated with pressure products. Sometimes the only 

 change is the granulation of the rims of the plagioclase, 

 as is shown by the white border surrounding the purplish 

 unaltered plagioclase core. In other places the alteration 

 in structure may be traced through flaser gabbro, augen 

 gabbro, gabbro schist to a garnetiferous gneissoid rock.
