264 GEOLOGY OF THE NABRAGANSETT BASIN. 



WARREN NECK. 



About a mile north of Chases Cove, on Kickamuit River, the shore 

 line is deeply indented and a valley extends thence northward for about a 

 third of a mile. West of this valley are abundant exposures of conglom- 

 erate, forming two hills over 60 feet high, the pebbles being rather large, 

 often 1 foot in length. There are very few interbedded sandstones, and 

 these lie almost horizontal or dip slightly eastward. The northern hill lies 

 southwest of the angle of one of the main roads of the neck. Northeast 

 of this angle a low ridge of conglomerate in the open fields continues the 

 exposures, increasing in elevation northward on entering the woodland. 

 Two-fifths of a mile northeast of this ridge, along the railroad, the con- 

 glomerate is exposed again, showing a strike of N. 30° W., dip 45° E. 

 Hardly a quarter of a mile eastward the conglomerate has a strike of N. 

 20° W., dip 30° E. Between these two exposures southward, in the fields, 

 occur others with approximately the same strike and dip. Farther eastward, 

 however, the fairly abundant exposures along the south side of the railroad 

 show, eastward, first, a northeast strike and a western dip, changing 

 rapidly to an almost east-west strike and a northward dip of perhaps 20° 

 to 30°. 



CONGLOMERATES AND SHALES OF SWANSEA AND WARREN, NORTH 



OF THE NECKS. 



The road from Coles Station to Luthers Corner leads first northward, 

 then eastward, and then northward again. Just south of the second angle 

 of the road, along the shore, the conglomerate has a strike of about N. 60° E., 

 dip low northward. Northward along the west side of the road are several 

 exposures, the most southern of which has a strike of about N. 70° E., dip 

 about 50° N., the strikes farther north being also decidedly eastward and 

 the dips north. East of these exposures a road leads eastward to Fall River. 

 Where it crosses Coles River there are exposures on both banks. Exposures 

 also border both sides of the river for about a quarter of a mile northward ; 

 and southward, below the bridge, exposures are found in the channel and 

 on the west bank. The strike for all of these exposures is about N. 45° E., 

 dip 20° NW. Along the road leading from the western side of the 

 bridge northward exposures are abundant on both sides of the road, show-
