GEOLOGICAL [SKETCH BY NANSEN. 



31 



According to what has been said before in this sketch, there should 

 probably be the following succession of Jurassic sedimentary strata at Cape 

 Flora, in descending order (cf. fig. 7): 



280 m. A plant-bearing bed of sandstone, 

 (900 feet) probably between fourth and third, or 

 between fifth and fourth tiers of basalt 

 (iig. 7, fc). 



210 m. A plant-bearing bed, principally of 

 (700 feet) sillcious rock, between third and sec- 

 ond tiers of basalt (fig. 7, I). 



200 m. 

 (660 feet) 



In the soil on top of the first or low- 

 est tier of basalt, a Jurassic forest has 

 been growing, branches and trunks of 

 which have been found, in a carbo- 

 nized or charred condition, enclosed in 

 the second tier of basalt (fig. 7, be- 

 tween I and 11). 



175 m. Base of the basalt. 

 (575 feet) 



On top of Cape 

 Flora cliffs, north 

 of Elm wood (fig. 1, 

 fc), (The plant-fos- 

 sils found on a nun- 

 atake farther north 

 (fig. 1, i) belong 

 perhaps to nearly 

 the same horizon). 



In the cliffs above 

 Windy Gully (fig. 

 hi). 



On the south face 

 of Cape Flora cliffs. 



A specimen of Amino- 

 nites Lamherti (New- 

 ton) was found (by 

 Koettlitz) enclosed in 

 the basalt. 



Above Elniwood 

 (near fig. 1 d). 



175 m, 

 (575 feet) 



175 m. 

 (575 feet) 



Black shale 4 inches (in contact with 



the basalt and somewhat 



hardened). 

 Black shale IVa inch (not so much 



hardened). 

 Greenish grey shale 3 inches (not so 



much hardened). 

 A lighter coloured brownish soft clay, 

 the depth of which was masked by 

 the talus heaps (fig- 7, /). 



Soft clay 3 feet thick, immediately 

 below the basalt (fig- 7, f); and under 

 this clay a bed of basalt with lava- 

 like structure, 6 feet thick. 



No fossils found. 



No fossils found, but 

 Quenstedtoceras (see 

 Pompeckj) and Amm. 

 Lamherti possibly or- 

 iginate somewhere near 

 this horizon. 



East of Elmwood 

 (fig. 1, /, f)- 



Above Elmwood 

 (fig. 1, d). 



1168 m. Soft clay beds of great thickness, with Fossils found in situ, 

 (550 feet) bands of nodules of clay-sandstone described % Newton 

 yoov icci; ^^ ^g Amm. (Cadoc.)
