The marine Carboniferous of Nortii-east Greenl. and its Brachiopod Fauna. 527 



merate Section should lie about 50 m. lower than those at Koch's 

 Section). 



However, the profile is, evidently, not so simple as Jarner has 

 drawn it, i.e., a simple transgression with basal conglomerate and 

 an even transition through somewhat finer-grained sandstones to 

 limestones that are certainly marine. In the Conglomerate Section, 

 as summarized above, there have been observed, in addition to the 

 conglomerate, three different beds of sandstone stratified alternately 

 with limestone, and Wegener's diary notes mention an alternate 

 stratification of conglomerate and a light limestone Ч 



The unconformity which is characterized by limestone strata 

 with marine fauna covering the sandstone which contains a land 

 flora, is evidently not the effect of a simple process, but the trans- 

 gression has taken place very slowly under slight oscil- 

 lations. 



On the shore below the Mallemukfjæld there has been collected 

 a number of boulders containing fossils. Of these stones some 

 have been found W. of Koch's Section, and are connected with the 

 same rocks of that locality, and have been briefly mentioned above; 

 the others have probably been collected at the Mallemukfjæld itself, 

 where the ice-edge goes pretty high up on the side of the cliff. 

 These rocks present no agreement with the rocks in the two sect- 

 ions already mentioned, but are, in all certainty, derived from strata at 

 a higher level. On the other hand, these free-lying stones that have 

 been collected at the Mallemukfjæld show far greater agreement — 

 both as regards their petrological character and their fossil contents 

 — W4th the rock specimens that were collected at the Eskimo Naze, 

 these, too, being only free-lying stones. The Eskimo Naze is the 

 outermost north-eastern point of Holm's Land, and lies a good 30 km. 

 north-east of the Mallemukfjæld. Here the shore is low and no solid 

 rock is seen there. 



The specimens that were found at these two places can be divided 

 into three different groups, viz. : 



a) coarse-grained limestone. 



b) fined-grained — 



c) silicified — 



' A quotation from Dr. Wegeners diary kindly communicated to me by Captain 

 Koch includes the following remark on this matter: "Kin genaues Profil unter 

 Berücksichtigung aller Bänder erwies sich sehr kompliziert, da alle Lagen an 

 den Übergangsstellen mehrfach wechsellagern".
