are not very common, these, as has been shown 
in describing the Morin anorthosite, are not 
distinct when the granulation is complete. On 
the other hand, the large remnants of plagio- 
clase, which occur abundantly in many places, 
point very strongly to an advanced stage of 
crushing. 
This gabbro intrusion is surrounded by a 
zone of rock intermediate in character between 
the gabbro and the surrounding gneiss and 
which probably represents a border facies of the 
gabbro. This gabbro is cut by a few small black 
dykes of post-Archaean age.

This village of New Glasgow is situtaed near 
the western side of the long arm-like apophysis 
of the anorthosite intrusion referred to before. 
Here the anorthosite, under the great pressure 
exerted upon it from the east, has undergone 
great deformation. It is much finer in grain 
than the anorthosite at Ste. Margene: 
thoroughly granulated and has a_ distinct 
foliation. As already explained, the an- 
orthosite loses its colour under ~ these 
conditions and whenever the iron magnesia 
minerals are sufficiently abundant to make the 
structure evident, the rock is seen to be distinctly 
foliated. The roches moutonnées of white 
anorthosite, which protrude through the drift 
in all directions, form a striking feature of the 
landscape. 
These are well seen along the road which 
runs north from the railway station and follows
