1898- 1902. No. 36.] SUMMARY OF GEOLOGICAL RESULTS. 



Also on the north side of Princess Marie Bay, Schei found the lime- 

 stone of Norman Lockyer Island. It is overlaid by sandstones and a 

 limestone-conglomerate. Farther to the north on the coast of Kane Basin 

 Schei has not been, but from there we have the important observations 

 made by Feilden and De Ranee, i 



The other district in which Schec observed the oldest paleozoic 

 sedimentary rocks was in the eastern part of the north side of Jones 

 Sound. On the western side of Fram Fjord (north of Smith Isl.), he found 

 above the Pre-Cambrian: I hght-coloured sandstone with diabase and 

 higher II yellowish magnesian limestone with sandstone layers. 



In the Havnefjord (Harbour-Fjord) district we find a basal sandstone 

 overlaid by 4—500 m. of limestone-conglomerates, limestones and shales, 

 and still higher 6 — 700 m. mostly brownish limestones. In the lower 

 part of these brownish limestones, at the South Cape on the west side 

 of the mouth of Havnefjord, were found Halysites catenularia Lin, 

 Strophomena sp., Maclurea sp., the two last mentioned too fragmentary 

 for exact determination.- This fauna indicates a Trenton age, though 

 nothing can be said with certainty. As no fossils were brought from 

 tiie series below the brown limestone we have no direct proof as to the 

 age of the basal beds, o: no material for conclusion as to when the 

 paleozoic sea invaded this district. However, if we consider the vast 

 quantity of sediment lying below the limestones, and the predominance 

 of limestone-conglomerates which belonged to the most characteristic 

 rocks of the basal series of Bache Peninsula, it seems quite safe to 

 assume that also in the present Jones Sound district the sea had 

 invaded the land at earliest Ordovician time. Of some importance is 

 also the occurrence of diabase in sandstone above the Pre-Cambrian at 

 Fram Fjord, as this gives us conditions very similar to those at Cape 

 Camperdown. However, as the diabase is intrusive and not effusive, it 

 cannot be fully relied upon as a guiding zone. 



A fact that points strongly towards the conclusion mentioned is the 

 occurrence of an interesting structure found in a piece of limestone brought 

 by Schei from the east side of Havnefjord, taken from a locality near 

 the winter quarters of the „Fram" 1899 — 1900, and certainly from a 

 horizon far below the brown limestone and not far above the Pre-Cambrian. 

 (From the same locality were brought pieces of limestone-conglomerate). 

 The sti'ucture is illustrated in pi. I and is identical with what, together with
