shale, and thin greenish or white bands of sandstone, are dipping 

 eastward. Adjoining these sandstones, on the north, is Silurian 

 carbonaceous schist of the Cobequid group, separated by a fault 

 which may be traced down the beach in a S. 71 W. direction. 

 This is the main Cobequid fault, shown in Fig. 10. Other minor 

 faults are shown in the same map.

 sandstones. The sandstones appear along the gentle slope at the left-hand side of the 

 cliff. 



Cape Sharp. — To the east of Cape Spencer, Cape Sharp is the 

 first promontory. It consists of basalt, as does Black Rock on 

 the west (Fig. 13). On the north of Cape Sharp is a lowland 

 underlain by red Triassic sandstone and shale with occasional green 

 bands, and north of this is a rolling country underlain by Carbonif- 

 erous sediments. 



The basalt on Cape Sharp consists of one or more flows — 

 probably two flows — which dip to the south at an angle of about
