BROWNS POINT TO CHURCHS COVE. 283 



shore at low tide. A third of a mile south of the cove, along the shore, the 

 fissile green shale shows purplish coloring along certain beds, and in places 

 there seem to be fine bands of a dolomitic limestone showing a pinkish 

 coloring. The strike here is N. 8° E., dip 15° E. A quarter of a mile 

 southward the strike is N. 20° E., dip 35° E. At Churchs Point the shales 

 strike N. 15° E., dip 40° E. A third of a mile southeast, south of the 

 mouth of a small stream, there is an exposure too massive to indicate the 

 attitude of the beds. Farther south close observation shows a fine-grained 

 rock cleaved very much like that of the two hills toward the north, first 

 described; strike N. 30° E., dip 40° E. Massive rock occurs again a 

 quarter of a mile south of the stream last mentioned, in a small indentation 

 of the shore line; also at the projecting outline farther south, and at the 

 next two similar projections of the shore. The strike is apparently N. 10° 

 E., dip 60° to 70° E. North of the angle in Churchs Cove the rock has 

 again a more whitish quartzitic appearance; strike N. 10° E., dip 25° E. 

 A short distance south of the point where the shore line takes a southerly 

 trend the greenish shale is again exposed. Certain layers are tinged with 

 purple, and pinkish or light-red very thin dolomitic bands are again seen; 

 strike N. 15° E., dip 15° E. The greenish shales continue to be exposed 

 all along the shore as far as the granite area. Just north of the granite area 

 they are again frequently tinged with purple and also show the very thin 

 dolomitic bands. Their strike is N. 3° E., dip 20° E. The tingeing of 

 purple with the thin banding of dolomitic material suggests that these shales 

 are identical with the shales forming the western third of Newport Neck. 



A distance of about 50 feet intervenes between the above-described 

 shales and the next exposure of rock. This is a rather dark rock, con- 

 taining abundant brecciated fragments of a dark-greenish stone, and appar- 

 ently also fragments derived from a granitic mass. It strikes in a direction 

 about N. 40° E., and evidently follows the northern line of the granite mass. 

 It is believed to be a breccia formed during the faulting which brought the 

 shales and the granite into juxtaposition here. 



The green Little Compton shales are believed to be of pre-Carbonifer- 

 ous age. The granites on the south are also considered pre-Carboniferous. 

 The granites may, however, be more recent than the Little Compton shales. 

 In that case the shales near the contact would appear more massive and 

 more like hornstone, resembling the Dumpling rock south of Jamestown on 

 Conanicut.
