III.— The Geologically Recent Origin of the Surface Contour of Scandinavia and Finland, and its Lessons

Published online by Cambridge University Press:  01 May 2009

Extract

Let us now turn to the angular gravel itself, the so-called Krosstensgrus of the Swedes, which is formed in the main from crystalline rocks, from granite, and gneiss, hälleflinta or petrosilex, crystalline limestones, mica-schists, quartzite diorites, diabases, porphyries, etc. This angular gravel Erdmann not only pronounces to be moraine material, but the only moraine material in the country. How it is possible to correlate this angular drift with any kind of moraine material, or to explain the angular gravel of Sweden by the intervention of ice, I cannot understand, any more than I can understand the application of the same cause to the angular gravels of Southern England and Northern France.
