Geoland
Dolerite outcrops widely in an undulating ice overridden landscape; cover deposits are patchy varying from bouldery felsenmeer regolith to intermittent till |
patches; surface age is variable owing to remnant snow fields which behave as local nevee glaciers possibly reworking older surface deposits; the drift mantle is |
young |
