infilled basalt of reverse magnetization. The floor is covered
by a thick, partly coarse, conglomerate in which material
from the Old rocks is conspicuous. Then we find 2 or 3 very
fresh lavas, partly of globular structure, with normal magne-
tization. On this we find: at 190 m, moraine-like conglomerate,
covered by brown coarse conglomerate. These sediments are
together 20 m thick and are cut by a normal dyke. At 230 m,
normal basalt (not intrusive) rests on the conglomerate. The
conglomerate has considerable infillings but the basalt is very
fresh. There are a few more normal lavas, then primary fine
breccia, then a conglomerate covered at 270 m by two nor-

mal lavas. With the exception of the uppermost one metre
this conglomerate is assumed to be a tillite.
The (dipping) lavas are here cut by a horizontal erosion
plane at 290 m. On this is 3—4 m of reddish boulderclay with
numerous very beautifully striated and facetted cobbles and
boulders. This is finally covered by a very thick primary
fine breccia (tuff-breccia) whose magnetic polarity could not
be determined here. This formation extends to the summit
of the Kambur ridge (Figs. 24 and 25) and forms also a hill
farther east. Between the two is a valley in which a normal
lava has flowed at a height of 380 m.
In this section, then, there are found 3 glacial horizons.
The layers below the 290 m erosion level are deposited in
a valley or against a slope at any rate. Probably this erosion
feature is younger than the reverse group, although that is
not. certain. The freshness of the lavas, though, speaks for
that conception.
In Fig. 25 the Kambur ridge is shown from the west. At
