40 HANS KETTSCH. [1896. 



Geological notes from the Region to the North 

 of the Fæmund Lake. 



[ (A short Summary of the Contents.) 



The Fæmund-Lake lies at 62° n. 1. near the Swedish 

 border. A broad open valley at an altitude of 1800 — 2000 f. 

 stretches from[here to the North. On the Eastern side is the 

 series of Border-mountains attaining nearly 6000 f. (Sylene) ; on 

 the Western side we have a similar but less regular and not 

 so high mountain-range (Fongen about 4500 f.). The three maps 

 on p. 4, 38, 39 follow one after the other from South to North. 

 The white is covered ground. Cross hachures: dioritic rocks. 

 Oblique hachures: Greenish, finegrained, mostly schistose rocks 

 kindered to the dioritic rocks. Black: Olivine rock and ser- 

 pentine. Crosses: Granite. Dots: Conglomerate. Fine dotted 

 lines: Porphyric'gneiss. Dense vertical hachures: „Eeros schists". 

 Vertical hachures: „Hard schists". Finally there is also a sign 

 of limestone. 



The Beros schists consist of argillaceous mica-schists. Fos- 

 sils are not found in this region but it is likely, the Beros schists 

 will be determined as under-silurian (Ordovisian). Under the 

 designation „hard schists" are united quarzite, gneissic schists 

 and some hard horny rock („helleflinta u of the Swedish geo- 

 logists). These hard schists are probably older than the Beros 

 schists and may be grouped with the „Sparagmite" of Central 

 Norway.
