Rawson, and Cape Cresswell represent the axes of plication of the north 

 side of Greely Fjord? What are presumably Mesozoic deposits, as well 

 as Tertiary deposits (e.g. at Cape Murchison), are known to exist in the 

 radius of Fielden's w Cape Rawson beds," e.g. at Cape Baird and Antoi- 

 nette Bay. Is it not possible that these are indentical with the Mesozoic 

 shales and sandstones which were recognized at Eureka Sound? 



Hence, from what has been already said, both the Siluro-Devonian 

 series of sedimentary formations which exist in the south-west of Elles-

mere Land and the Triassic deposits further north have alike participated 

 in the dislocations. Some of these (should there eventually turn out to 

 be more than one system) must thus be later than the Triassic epoch. 

 On the other hand, the Miocene sand and lignite, which occur east of 

 Cape Blue Man, were laid down in an isoclinal transverse trough, where 

 they still lie horizontally, and are bordered by what are presumably 

 Mesozoic sandstones. Indeed, everywhere where Tertiary deposits were 

 noticed in similar positions, they all occupied a horizontal position. Hence 

 we are apparently justified in concluding that the most conspicuous in- 

 stances of dislocation are later than Triassic, but antecedent to Miocene." 



Cenozoic. 



Tertiary deposits were found in several places on the west side of 

 Ellesmere Land, as well as on the east coast of Heiberg Land (Skaare- 

 fjord.) They consist of very thick, light-coloured sandstones, shales and
