Norges kvartærgeologi. En oversigt.

Abstract

Forkortet:The first part contains an historical survey of the works of the Norwegianquaternary geologists in somewhat chronological order, commencing withJens Esmark (1763-1839), who as early as 1824 described the first morainesin Northern Europe, and stated that the Norwegian mountains had once beencompletely covered by a large ice-field that extended to the sea, and thatthe sea itself must have been a sea of ice.The second part deals with the successive formations of the quaternary period.Firstly the surface form of the land, with the various views compared:Kjerulf's, that the formation of fiord and valley may be ascribed to diaclasesor joints in the rock. Helland's with ice as the principal factor and Reusch's,by which running water is given great importance: the latest investigations ofOlaf Holtedahl seem to confirm Kjerulf's views. Next we have an account of theIce Age deposits. The third part gives a short review of the conditions of thesoils in various parts of the country.
