GEOLOGY 217 



' There are at Havnefjord, in Jones sound, above some layers 

 of quartz-sandstone, which entirely cover the gneiss-granite 

 there, a series of limestone conglomerates with marly schists 

 and pure limestones of a thickness of 1,200 to 1,500 feet. These 

 are again overlain by a series of beds at least 2,000 feet thick, 

 of hard, impure limestones, brown or yellowish-gray in colour, 

 and often remarkably heavy.' 



' At South cape, which is entirely composed of this brown 

 limestone, are found in the lower parts Maclurea sp., and 

 Holy sites sp., referable to the Middle Silurian, while west of it, 

 at Bjorneborg, the upper parts of the series contain badly pre- 

 served remains of Orthocerata, Corals, and Pentamerus cfr. 

 tenuistriatus. Hereafter the upper part of the limestone seems 

 to be equivalent to the older Upper Silurian (Landovery). This 

 brown limestone occurs from South cape westward to Kobbe- 

 bugten in Hell Gate, and is broken at Lille Sandor, tectonic 

 disturbance bringing up the underlying conglomerate series, 

 and even the Archaean.' 



' On the south side of Rendalen appears the brown limestone 

 of the capes, Series A, with a flat dip to the north-northwest ; 

 but on the north side of the valley is a division of dark schist, 

 Series B, lying conformably above the beds of brown limestone. 

 Associated with these schists, particularly in their lower and 

 upper parts, are numerous layers of pure dark limestone, fre- 

 quently fossiliferous. In Rendalen and in Kobbebugten, where 

 this same division also appears, a quantity of material was 

 collected, of which fifteen species are provisionally determined, 

 among them being Favosites sp., Strophomena cfr. euglypha, 

 Meristella in numbers, Rhynchonella cfr. ~borealis, Pentamerus 

 cfr. galeatus, Spirifer cfr. elevatus. The period of this divi- 

 sion in Series B is Wenlock.' 



' The upper part of Series B appears, among other places, at 

 the headland north of Tunneldalen, in Hvalrosf jord. Above a
