CODDINGTON COVE TO LAWTONS VALLEY. 319 



SHALE SERIES FROM CODDmGTO:N" COVE TO LAWTONS VALLEY. 



In the railway cut southeast of Coddington Cove the bluish-black shale 

 is exposed for a quarter of a mile. The cleavage dips 15° to 20° W. 

 In the most eastern part of the indentation at Coddington Cove black shale 

 is exposed again, the cleavage dipping 10° to 20° E. Three-quarters of a 

 mile northward, south of the angle of the shore directly east of Gould 

 Island light-house, the dark carbonaceous, often black, shale is seen in the 

 bank. It is much cleaved, the dip of the cleavage being low eastward. 

 Northward, in the concave curve of the shore, gray-blue sandstone is 

 interbedded with the coaly shale. The cleavage still dips only 5° to 10° 

 E., but the real stratification shows strike N. 21° E., dip 25° to 30° E. At 

 the north end of this cove the most western part of the shore line shows 

 more of the carbonaceous sandstone interbedded with coaly shale; strike 

 N. 12° W., dip about 60° E. A few fern-leaf impressions occur in the 

 shale here. Over the sandstone lies more of the coaly shale. The sand- 

 stone and shale continue to be exposed for half a mile northward, the strike 

 changing at the north end to N.-S., dip 50° E. The cleavage is low 

 west. Along the railroad southward, near the north end of the cut, greenish 

 shale and sandstone occur, the latter including thin layers of fine conglom- 

 erate. These greenish rocks evidently belong in the blue shale series, 

 but overlie the shore exposures. Along the east- west road northward, 

 nearly half a mile from shore, black shale is exposed. Where the next 

 creek northward crosses the road from Newport to Bristol Ferry, the 

 greenish-blue shale series is exposed in the creek bed west of the road. A 

 little south of the mouth of this creek coaly shale and sandstone are found 

 in numerous fragments in the banks, as though occurring- in situ farther 

 back from the face. 



East of Can's Point and south of Lawtons Valley the north end of 

 the railway cut shows coaly shale and carbonaceous sandstone; strike 

 N. 15° E., dip 15° E., as far as could be determined; the exposure is not 

 satisfactory. The blue shale series is exposed along Lawtons Valley, 

 about half a mile south of the point where this valley crosses the Newport 

 raod, and where the east-west road leaves the Newport road eastward 

 for the Glen region on the east side of Aquidneck. Up the road eastward 

 the blue-black shales are exposed as far as the brow of the hill. A little
