428 PROF. NORDENSKIOLD, EXPEDITION TO GREENLAND. 



(5.) Hard grey sandstone, almost like porphyry, inclosing round 

 nodules of small stones and fragments of coal (100 feet). 



(6.) Alternating layers of sandstone and carbonaceous shale, 

 with seams of coal, layers of harder shale, impressions of 

 leaves, etc. (100 feet). 



(7.) Black shale and grey sandy shale with sandstone seams, no 

 fossils (300 feet). 



(8.) Sandstone of uniform yellow colour, the upper part, for a 

 depth of 200 feet, interstratified with grey shale, sand- 

 stone, and coal seams (300 feet). 



(9.) 



2. Angiarsuit. — Yellow sandstone, interstratified with grey 

 shale, with seams of coal and impressions of plants ; the same 

 stratum as No. 8 at Ekkorfat (Fig. 9). At Ekkorfat the strata, 

 with the exception of occasional irregularities, dip S.W., so that 

 nearer Karsok the yellow sandstone (8) reaches to the level of 

 the sea. We thus had an opportunity of collecting fossils 

 from this stratum, at a place called by the natives Angiarsuit ; 

 and these decidedly belong to the same formation as the fossils 

 from the lower strata at Ekkorfat. 



3. Avkrusak. — Fine impressions of plants are found here, near 

 the shore, immediately under the sandstone, in horizontally strati- 

 fied shale. 



4. Karsok. — The coast-land here, as has been mentioned above, 

 is occupied by gneiss rocks, which, at a height of eight or nine 

 hundred feet, are covered by a layer of shale containing fine im- 

 pressions of Ferns. The shale, however, at a short distance is 

 covered by gravel, so that the formation is exposed here only for 

 a very limited distance, close to the Karsok river. 



5. Pattorfik. — For a distance of six English miles from Karsok 

 the coast towards the fjord is occupied by gneiss ; but on the 

 other side of the river, at Pattorfik, first shales and then sand- 

 stones reappear close to the shore ; the former with particularly 

 beautiful fossils, found principally in the beds nearest the gneiss. 

 No extensive sections are however to be met with here, for the 

 perpendicular exposed cliff", some yards above the sea-level, is 

 covered with detritus of basalt, often hardened to a tuff'-like mass, 

 and inclosing the large subfossil shells mentioned above (p. 409). 



6. Kome, or more properly Kook. — The former name, though 

 grammatically wrong, ought howevet to be retained, as having 

 been already introduced into science. The lowest portion of these 

 strata forms on the shore an abrupt terrace, from 80 to 150 feet 

 high. Higher up the strata terminate in a gravel-covere4 slope, 

 scored by a number of deep ravines, which offer very clear sec- 

 tions of the various strata of the formation, for the most part 

 nearly horizontal, or slightly dipping inwards. The series is as 

 follows (beginning at the top) : — 



On the brow of the hill - Basalt. 



About 1,500 to 1,200 feet above f Thick banks of gravel, 

 the level of the sea. \ concealing the strata.
