Fossiliferous gytje- and clay-deposits. 



(Fossilførende Gytje- og Leraflejringer.) 



On pp. 131—137 an account is given of various fossil-containing gytje- and 

 clay-deposits, which either by their fauna or by their situation reveal that 

 the period of their formation lav far back in thc Quaternary Period, though 

 the actual point of time cannot at present be given more exactly. On pp. 

 133—134 lists are given of the piants found in gytje masses in the lower 

 moraine in Copenhagen Free Harbour; the animal remains mentioned on p. 

 134 from the same mass are for the most part cited after A. C. Johansen 

 (1904). 



On p. 13.") are noted the plant remains from the Corbicula bed at Førslev- 

 gaard, on p. 137 the plant remains from elay boulders in the lower moraine 

 in the Free Harbour and Valby Hakke, the last being of an aretie character. 



Interglacial deposits. 



(Interglaciale Aflejringer. ) 



It appears from my investigations that Jutland contains a number ot 

 plant-containing interglacial lavers. In 1899 I described a number of occur- 

 rences of interglacial diatom-earth (at Hollerup, Fredericia, Trælle and Vejle); 

 in a preliminary note (1904 & 190.")) I stated, that in several bogs in the neigh- 

 bourhood of Brørup in sonthernmost Jutland near the German boundary, 

 I had found fruits of a North American Cyperacea, Dulichium sjxilhaceiun 

 Pers., which no longer grows in Europe and had nol been known there 

 before my investigations, and again, in these preliminary reports I noted 

 the discovery of Brascnia purpurea, Picea excelsa, Carpinus betalus and other 

 interglacial characteristic fossils in these bogs. 



In 1907 the proprietor Fritz Momsen, Skovlyst near Brørup, found on 

 digging a well at Brørup Station that a laver of peat was laid bare at a depth 

 of ca. 5 m. below the surface of the earth, and in the following year I in- 

 vestigated this and numerous other interglacial bogs, chiefly in the neigh- 

 bourhood of Brørup. These bogs have always been noticeable in the country, 

 as a Hat, bowl-shaped depression occurs in the soil over the intei-glacial bog- 

 basin, the peat in the course of time becoming strongly compressed under 

 the weiaht of the over-lving diluvial lavers. 



Bog in village at Brørup station. 



(Mose i Brørup Stationsby.) 

 The section was: 



0.6 m. waste-filling, 



o.o - sand with a few stones, 



0.3 - humous, clayey sand, »transition laver«, 



2.o - peat, 



0.6 - gytje, 



0.5 - + freshwater sand.
