112 GEOLOGICAL AREAS OF CANADA. 



amjgdaloidal trap ranges continuously, in the form of a bold line of 

 cliffs, along ths shore of the Bay of Fundy from Brypr's Island to- 

 Cape Blomidon, with outlying patches in Partridge Island, &c., and 

 at Cape d'Or on the opposite coast. A layer of tufaceous material 

 marked by green cupreous stains, arising from the decomposition of 

 imbedded bunches of copper-glance, occurs very generally between 

 the sandstone and the overlying trap. Zeolites and other character- 

 istic trap minerals are abundant in the latter at many spots. 



2. The Newport and Truro Area. — This subdivision occupies the 

 country around Minas Basin and Cobequid Bay, extending north- 

 wards to the Cobequid mountain range, southwards to the northern 

 edge of the Atlantic metamorphic region, and eastward to the slopes 

 of the syenitic ranges in the south-east of Colchester Cou.nty. It 

 thus includes the countiy around Windsor, Newport, Walton, Mait- 

 land, Truro, and Parrsborough, with the valleys of the Kennetcook, 

 Shubenacadie, Stewiacke, and Musquodoboit rivers, more especially.. 

 Its strata belong, for the greater part, to the Lower Carboniferous 

 Series, and consist of red and other-coloured sandstones, dark shales 

 holding numerous coal-plants and fish remains, marls, and limestones. 

 The latter strata contain an abundance of Carboniferous bracliiopods- 

 and other fossils ; and in many places, as in the vicinity of Windsor,. 

 in the cliffs of the St. Croix River, at Newport and Walton, along- 

 the Shubenacadie, &c., they are associated with beds (and occasional 

 veins) of anhydrite and gypsum. A few comparatively limited 

 patches of Middle Cai-boniferous strata overlie these lower beds here 

 and there along the edge of the Cobequid Range, and in places in the 

 valleys of Kennetcook and Stewiacke, but they appear to contain 

 merely thin seams of coal, of value only as a source of local supply. 

 Both the north and south shores also of Cobequid Bay are bordered 

 by soft red sandstones and conglomerates of assumed Triassic age. 

 These rest unconformably on the prevailing Lower Carboniferous 

 formations of the country ; and in places, as at Gerrish's Mountain 

 and elsewhere, they are overlaid by masses of amygdaloidal trap. 



3. The Cobequid Mountains Area. — This section of the Province' 

 forms a wild but thickly-wooded mountainous district, of an average- 

 elevation of from 1,000 to 1,200 feet above the sea. It ranges, 

 roughly, from Cape Chignecto in the west, to the Carboniferous dis- 

 trict of Pictou in the east. Southwards it is bounded by the New- 

 port and Truro area, and northwards by the Cumberland coal region. 

 The Cobequid range is composed essentially of syenites and related
