THE ACADIAN TRIASSIC 255 



shown in Fig. 27. Above the North Mountain basalt comes the 

 Scots Bay formation, the youngest formation in the Newark group 

 of the Acadian area. The Scots Bay formation is exposed on the 

 south side of the Bay, as shown in Fig. 27. 



The eastern extremity of Minas Basin, east of Economy Point 

 (the area shown in Fig. 23), also forms a syncline which has been 

 disturbed by faulting at various points. The beds of red sandstone 

 on either side of Cobequid Bay dip toward the bay at angles of 

 about 3°-5° except where they have been tilted by faulting. This 

 gentle dip must simulate that of the strata when they were first 

 deposited in the slowly subsiding geosyncline. 



A syncline, which is well shown in a shore section, is found at 

 Quaco, between West Quaco and Melvin's Beach, on the north 

 side of the Bay of Fundy (see cross-section BB, Fig. 7). The 

 sediments of the Quaco section are readily identified by the Quaco 

 conglomerate in the center. This conglomerate is exposed on the 

 shore near Vaughan Creek with a dip of 30 to the north and again 

 a mile inland (northwest) with a corresponding dip to the south. 

 The syncline is cut off obliquely on the north by a fault in such a 

 way that the axis of the syncline is shown in the shore section near 

 Melvin's Beach, but the Quaco conglomerate of the northern limb 

 does not reappear. 



At Split Rock a low anticline is shown, at Martin Head a syn- 

 cline, and at Waterside an anticline and the adjoining syncline. 

 In each of these cases the folds are cut off by faults. The folds 

 are at a low angle with broad arches or troughs. 



Cape d'Or shows a small syncline in the basalt flows where the 

 basalt ridge turns, from its east-west course, to make the Cape on 

 the south. Horseshoe Cove has been formed at the axis of the 

 syncline. The basalt is also faulted as is shown in Fig. 12. 



Everywhere in the sea-cliff exposures there are minor flexures 

 in the Acadian Triassic, both in the sediments and in the igneous 

 rocks. In Fig. 19, an example of the folds in the sediments west 

 of Five Islands is given. In the North Mountain basalt, gentle 

 folds are shown at Scots Bay, where the Scots Bay formation is 

 preserved in synclines (Fig. 29), and at Digby Gut, where a long 

 syncline is shown at Victoria Beach.
