Faults. — Two main faults are recognized (Fig. 25). The 
northern of them follows the south coast of Sermilik Fjord, 
north of the mountain group of Ilimausak, and farther to the 
northeast traverses the northern part of the peninsula between 
Sermilik and Tunugdliarfik, where it is apparently replaced by 
a number of smaller dislocations, which for the most part lie

Farther eastward the fault-line follows the Kiagtut valley, but 
here it is concealed by the Quaternary deposits and the glacier. 
The southern main-fault may be traced from Kangerdluarsuk 
to the country south of Igaliko; its continuation east of the 
Igaliko Fjord is entirely covered by alluvial deposits. Minor 
faults are observed at several places within the sandstone ter- 
ritory (see Fig. 24, p. 264).
