paper is summarized below in treating of the age of the Acadian 

 Triassic. As the plant remains appear to be similar to those found 

 at Quaco, the sediments in the two areas may be correlated with 

 each other. 



Waterside. — On the north side of Chignecto Bay is a strip of 

 Triassic at Waterside, 20 miles northeast of Martin Head. The 

 length of the strip is 

 about 4 miles, ex- 

 tending from Den- 

 nis' break-water on 

 the west to the east- 

 ern end of the marsh 

 at Little Rocher on 

 the east (Fig. 10), 

 but the length of the 

 actual exposures of 

 Triassic sediments is 

 about 1 1 miles. 



The structure of 

 this area is anticlinal 



on the west and synclinal on the east, with the axis of the syncline 

 at the Waterside wharf. The dip of the folds is gentle, exposing 

 only 320 feet on the eastern limit of the anticline. On the west,

Fig. 11. — Geologic cross-section, CC, from Waterside, on the north, through 

 Cape d'Or, across Minas Channel, and through North Mountain. A, pre-Cambrian ; 

 B, Meguma series (pre-Cambrian) ; SD, Cobequid group (Silurian, cut by Devonian 

 igneous rocks); D, Devonian; C, Carboniferous; T, Triassic. The major fault of 

 the region is shown in the center of the section, where the Carboniferous and Triassic 

 are dropped down against the Cobequid group. 



the Triassic is faulted against a sheared Carboniferous conglomer- 

 ate, but the contact is concealed by a Pleistocene delta deposit. 

 This same fault probably bounds the Triassic area on the north 

 and east, but it is not again exposed.
