south-west point of the sandstone area the sandstone-covered 
surface of the granite lies about 200 meters above the sea. 
The junetion between the sandstone and the granite is 
exposed along the whole of this distance and the granite is 
seen to be older than the sandstone. The lowermost beds of 
the latter are granite-conglomerate or at some places arkose. 
It is of interest to note, that the sandstone gradually as- 
sumes its usual red colour as we get further away from the 
newer igneous rocks. At S. Siorarsuit, directly at the contact 
with the syenite, the sandstone appears as a snow-white, very 
compact rock, with numerous veins of transparent, colourless 
quartz. These veins may be from 2 to 10 centimeters broad 
and their course is quite irregular; they end at a short distance 
from the syenite. The apophyses sent into the sandstone by 
the syenite can be followed to a considerably greater distance 
and, like those mentioned from Kangerdluarsuk, contain a great 
amount of quartz. The white colour is still retained by the 
sandstone at a distance of several hundred meters from the 
syenite, but at a still greater distance red portions begin little 
by little to appear; it is the lowermost beds of the sandstone 
which first show this change in appearance. At the point 
furthest to the south-west the lowermost 50 meters of the sand- 
stone are of the ordinary red colour, but even here the upper 
sandstone beds have been discoloured. 
Towards the north-east the sandstone beds and the in- 
trusive sheets of Nunasarnausak border upon the great igneous 
complex. As the figure (p. 61) shows, the sandstone is not in 
direct contact with the nepheline-syenites but is separated from 
them by a zone of augite-syenite. This is the continuation of 
the earlier mentioned augite-syenite of Kangerdluarsuk and has 
almost the same general character. It should be mentioned, 
however, that the syenite at the shore by S. Siorarsuit has a 
reddish colour for a short distance and its felspar crystals 
show a strong tendency to assume a form which gives short
