266 A. H. BROOKS — RECONNAISSANCES IN SOUTHEASTERN ALASKA 



The Mesozoic beds in the province under discussion would seem to 

 correspond to the Cretaceous of the Queen Charlotte islands, both in 

 stratigraphical position and lithologic character. Dawson notes a period 

 of folding which succeeded to the deposition of the Cretaceous. The 

 Tertiary rocks described by hifxi are chiefly volcanic, and are provis- 

 ionally assigned to the Miocene. 



On the lower Skeena river and in the vicinity of Port Simpson, Daw- 

 son found a metamorphic series, made up of mica-schists and some 

 limestones, closely associated with gneisses. These would seem to be 

 the southern extension of the Ketchikan series, part of the belt of 

 argillites which lie adjacent to the granite of the Coast range.
