CARBONIFEROUS AREA OP BRISTOL NECK. 261 



POPASQUASH NECK. 



A long ridge of sandstone lies northwest of Ushers Cove, first trending 

 northward, then northeast, and then more northerly again. It is of bluish 

 color. No satisfactory strikes and dips could be determined, although the 

 exposure is large. 



BRISTOL NECK. 

 CARBONIFEROUS AREA. 



The lowest Carboniferous exposures on the neck consist of coaly 

 black shales, opposite the Brothers and Deyers Rock, where the railway 

 begins to turn toward the southeast, leaving- the shore. The strike seems 

 to be N. 10° W., dip 40° E. Species of Annularia and ferns occur in the 

 rock. The same black shales are found three-fourths of a mile farther south- 

 east, in the railway cut, where the strike is northwest and the dip northeast. 

 Above this coaly shale, exposed along the shore a quarter of a mile north 

 of the Brothers, lies sandstone containing black shaly layers showing a 

 strike of about N. 10° W., dip 40° E. Northeast of these shore exposures, 

 east of the railroad, is a high ridge of bluish sandstone, whose strike and 

 dip can not be determined, although the dip is probably eastward and the 

 strike probably of such a character as to connect this exposure with a set 

 of sandstone exposures farther south. This set of sandstone exposures 

 begins on the hillside east of the Brothers and of the railroad. It strikes 

 at first about N. 20° W., dipping 20° E. In the exposures southeast of 

 this locality the strike becomes more and more nearly east-west until, in a 

 quarry just west of the Warren-Bristol road, it is about N. 85° W., with a 

 dip of 20° N., the strike becoming perhaps N. 80° E. just before reaching 

 the road. 



Above this sandstone, toward the north, lies conglomerate. The most 

 conspicuous exposure is less than half a mile south of Jacobs Point, just 

 east of the railroad. The conglomerate here has a thickness of at least 20 

 feet. Its dip is low eastward, as may be seen by sandstone layers near its 

 northern end. The pebbles are of sandstone and are often 6 to 1 inches 

 long. The other conglomerate exj3osure lies 1/500 feet southward, indicat- 

 ing by its position relative to the other exposure a strike of N. 10° W. It 

 forms a small knoll in an open field. East of the region between these two
