PETROGRAPHY 
OF THE IGALIKO REGION. 
INTRODUCTORY. 
The district to be described in this chapter extends round 
the eastern ramifications of the Tunugdliarfik and Igaliko Fjords. 
It includes the area shown on the index map (Fig. 20), and given 
on a larger scale (about I : 212000) on the geological map 
(Pl. IV). 
From a topographic point of view the district offers con- 
siderable variation. The tracts lying west of the Tunugdliarfik 
Fjord and the area between this fjord and the inner end of the 
Igaliko Fjord are rather low, and consist mainly of sandstone 
plains on which grass grows more prolifically than is usually
