Gold. 
A few flakes of gold are reported to occur in the upper 24 m (79 feet) 
of the Josva vein and the small gold content of the chalcopyrite occurring 
with the Ivigtut cryolite is recovered. Quartz veins, on the whole, 
are rare in Greenland and these are, as a rule, but siliceous pegmatites. 
Although large bodies of pyrite are unknown, slightly auriferous quartz- 
pyrite veins, pyrite veinlets and pyrite impregnations exist. The rocks, 
on the whole, are rather unfavorable to the discovery of important 
gold deposits. 
The gravels have suffered but little concentration and important 
placer deposits are not to be expected. Small bodies of marine beach 
gravels and isolated bodies of pre-glacial gravels, protected in rock 
basins are, however, in instances well concentrated. Prof. Т. С. CHAMBER- 
LIN (“Jour. of Geol.” Vol. III 1895) reports the presence of a driftless 
area near Inglesfield gulf in which also the gravels are presumably well 
concentrated. 
Lead and zinc. 
As limestone is a rather uncommon rock in Greenland, the chances 
are against the discovery of large zinc or lead deposits. 
Galena and blende occur as impurities in the cryolite at Ivigtut 
and formerly a thin vein of argentiferous galena was unsuccessfully 
worked there (see p. 18). On Inugsuk Peninsula, just south of Ivigtut, 
are several veinlets cutting ancient sedimentary schists. The vein 
filling consists of quartz, in part crustified, a little siderite, fragments 
of wall rocks and sparse aggregates of blende, galena, chalcopyrite and 
pyrite. Zine blende and galena are fairly common in the Julianehaab 
district!), usually in close association with soda syenite pegmatites. 
Willemite occurs in a quartz vein at Musartut near Julianehaab cutting 
Devonian sandstone in the vicinity of igneous rocks. 
Chrome-iron ore. 
Chrome iron ore is an accessory mineral in a number of dunite 
masses which are particularly common in the general vicinity of Sukker- 
toppen. In the mass at the head of Tasiusarsuak fiord are a number 
of small lenticular bodies of dense fine-grained or coarsely crystalline 
chromite. In certain lenses olivine is intergrown with the chromite, 
but even in such cases the contact between the dunite and the chromite 
segregations is sharp. Similar chromite lenses occur in the dunite at
