feet) on either side has metamorphosed the coal and carbonaceous shale 
into respectively amorphous graphite and graphitic schist. This graphite 
is platy in structure, soft, very fine grained and of high grade. At sea 
level is one bed of platy graphite 0.4 m (1!/, feet) thick, up the cliff 
12 m (40 feet) at the coal seam horizon is а bed of similar graphite 
from 0.5 to 0.6 m (11/, to 2 feet) thick. Microscopic study of a specimen 
from the latter place shows a platy mass of amorphous graphite with 
here and there a grain of what appears to be chalcedonic quartz. 
The shale near the peridotite has been metamorphosed to a gray 
hornstone. 
About 3 km (two miles) south of Kaersut, some 400 m (1 300 feet) 
above sea-level, is a thick horizontal sheet of similar peridotite intrusive 
in similar sedimentary rocks. Among the sedimentary beds above this 
sheet are dark gray graphitic shales of impure quality, and а thin bed 
of fairly good amorphous graphite. They appear to vary from ca. 1 dm 
to 0.6 m (a few inches to two feet) in thickness. The sandstone near 
the flat intrusive has vertical columnar partings. Probably from this 
or one of the other occurrences in the vicinity, Captain G. W. Ввоск- 
DORFF, in 1850, mined graphite by stripping the morainal covering. 
He is reported to have taken to Europe in his ship some five tons of 
graphite. 
М№овозтвом") states that three samples of graphite from Kaersut 
after being dried at 120 С. contained from 93.7 to 95.68 % carbon, 
0.22 to 0.69 % hydrogen and 3.6 to 4.92 % ash. (largely silica, iron 
and some alumina oxide). 
Graphite also occurs at Niakornat, and about 1863 was mined on 
a small scale by Eskimos. According to Krantz, the graphite lies about 
5 km (three miles) southwest of the settlement at an elevation of 525 m 
(1 725 feet). There are two beds of graphite dipping 20° S., the lower 
of which is almost 1.5m (five feet) thick, and contains, as does the 
unaltered carbonaceous shale, some nodules of lime carbonate and pyrite. 
The upper bed is 0.75 m (21/, feet) thick and is a lenticular body cut 
off at one side by a peridotite dike. Here, as elsewhere in the vicinity 
of these graphite deposits, are many graphite fragments in the morainal 
deposits. This Niakornat graphite is, heavier and more shaly than 
that from Kaersut and is hence of scarcely as good quality. 
Although the material is high grade amorphous graphite, an ex- 
ploitable body of this type will presumably not be found. As elsewhere 
stated (p. 53), the coal beds (of which the graphite is the metamorphosed 
equivalent) are lenticular in form, and are rarely over one meter (3 feet) 
thick. Dikes metamorphose the coal only a short distance from their
