Stratigraphical and Paleontological Studies of Interglacial Fresh-water Deposits in Jutland and Northwest Germany

Abstract

With the publication of "Bidrag til Danmarks tertirere og diluviale Flora", N. Hartz brought to a conclusion his fundamental investigations or interglacial bogs in Denmark, the bulk of which belongs to the so-called Brorup type; that is to say, interglacial deposits lying in a basin recognisable as such relative to the present surface of the country, and covered by layers of sand, grayel or clay of nonglacigenous origin. For some years after, the questions associated with these formations were regarded as solved in all essentials. Supplementary investigations of the stratigraphical position of these bogs in relation to the extent of the last ice sheet occasioned no alteration in this view, as regards the deposits themselves. But just at the time when these last investigations were being carried out, a starting point was furnished for those further investigations which will be dealt with in the following pages.
