THE ACADIAN TRIASSIC III 



Wolfville-Scots Bay. — The Wolfville sandstone outcrops on the 

 exposed points between Wolfville and Pereau River, the most con- 

 tinuous exposure being near Kingsport. The sandstone contains 

 occasional conglomerate beds and red shales. The proportion of 

 shale to sandstone gradually increases toward Blomidon. The 

 shale in this locality is largely a red clay, with occasional green 

 bands, persisting horizontally throughout the exposure. The 

 general dip of the strata is 5°-io° northward. Small faults are 

 numerous. 



About midway between Kingsport and Pereau River, Haycock 

 found fragments of well-consolidated fossiliferous red shale in till, 

 overlying the Triassic. 1 The fossils are Estheria ovata. Dipping 

 under North Mountain are poorly consolidated Blomidon shales, 

 with the characteristic thin green beds at distances of 10-20 feet. 



The Blomidon shale continues around the hook of North 

 Mountain beyond Cape Blomidon, but not as far as Amethyst 

 Cove. At the latter locality, basalt cliffs, partly columnar, rise 

 abruptly from the sea to a height of 300 to 400 feet. These cliffs 

 are kept vertical by frost action on the vertical joint planes parallel 

 to the shore. 



Two basalt flows are visible at Amethyst Cove, dipping gently 

 northward, with undulating folds. The collecting place for 

 amethysts is in a greatly veined area about 100 feet below the top 

 of the lower flow. 



Scots Bay-Bennetts Bay. — In the region around Scots Bay 

 there are two points of especial interest: first, the origin of the 

 curve in North Mountain at this point, and, secondly, the presence 

 of the Scots Bay formation overlying the North Mountain basalt 

 along the southeast side of the Bay. Furthermore, the structural 

 evidence furnishes a clue to the former thickness of the younger 

 formation. 



The curve in North Mountain is formed in a syncline pitching 

 down to the west, and in the nose of this syncline Scots Bay has 

 been eroded (see Figs. 27,28). The basalt flows of North Mountain 

 dip toward the Bay on all sides at angles of 3°-5°. The topographic
