equal distances between. The outer appearance of the whole 
mountain-mass is that of a very regular stratified sedimentary 
complex. Though the strata are highly crystalline one might 
be inclined to suppose, on first observing them, that they are 
of sedimentary origin — an explanation of this kind has indeed 
been suggested by several previous observers. As a matter of 
fact, however, the strata are alternating white, red and black 
sheets of coarse-grained igneous rocks belonging to the family 
of nepheline-syenites. 
Above the steep wall facing the fjord there is a somewhat 
undulating plateau at about 400 meters above the sea, and be- 
hind the plateau rises the granite mountains of Iviangusat (Pl. V,

absolutely barren waste, as the white sheets of the kakortokite 
crumble even more rapidly than the naujaite; not a herb is to 
be seen and not even the lichens are present to darken the 
colour of the stone. The regular alternation of the variegated 
sheets is continued into the rounded eminences of the plateau: 
round about these the outerops of the black sheets appear as 
conspicuous, large rings which show a slight inclination towards 
the fjord. The surface of the ground thus obtains the charac- 
teristic markings which have given rise to the name Kringlerne 
(ring-twisted cakes). 
A section north-west—south-east through Kringlerne (Fig. 6) 
shows, that the inclination of the kakortokite sheets is some- 
what variable, and that the sheets are somewhat undulating.
