110 GEOLOGICAL AREAS OP CANADA. 



corrugated — the enclosing rock presenting, necessarily, a correspond- 

 ingly convoluted structure. The more important localities, or " dis- 

 tricts," in which these gold deposits have been recognized, are as 

 follows : — (i.) The Lunenherg district, including the Ovens area, &c. ; 

 (ii.) the Waverley, Oldham, and Renfrew district, north of Halifax ; 

 (iii.) the Uniache district; (iv.) the Tangier district; and (v.) the 

 Sherbrooke and Stormont district, including Wine Harbour, Country 

 Harbour, &c. 



The granite areas lying within this southern metamorphic region 

 have not yet been thoroughly explored, so that eventually many 

 apparently isolated masses will probably be found to constitute con- 

 nected bands. Those at present recognized occupy the following sites : 

 The country around Barrington and Shelburne, north and north-east 

 of Cape Sable ; the more southern portions of Digby, Annapolis, and 

 King's counties ; the Aspatagoen promontory between Mahone' Bay 

 and Margaret Bay ; the country around Halifax, especially north and 

 west of the city ; the lower portion of the Musquodoboit valley, and 

 adjacent country to the east ; the south shore of Chedabucto Bay and 

 the country westward to the vicinity of Sd. Mary's River. 



(2.) The Northern Carboniferous District.'^ — This region extends 

 along the Bay of Fundy, and throughout all the northei-n, centi-al, 

 and eastern portions of Nova Scotia, including the Island of Capo 

 Breton. 



In its general features it presents a number of detached Silurian 

 (and Devonian *? ) areas, separated for the gi-eater part by lidges and 

 mountainous masses of syenites, and surrounded by areas of Car- 

 boniferous strata. The .Silurian and Devonian rocks are mostly 

 tilted at high angles, and are altered more or less by metamorphic 

 action. The suiTOunding Carboniferous strata belong partly to the 

 Lower division, but chiefly to the Middle or Productive portions of 

 the series, and in many localities they contain important beds of 

 bituminous coal, some of the seams being of unusual thickness. In 

 addition to these strata, some comparatively narrow strips of Triassic ■ 

 sandstone, associated with vast trappean overflows, range along the 

 Bay of Fundy and the shores (in part) of Cobequid Bay. Boulder 

 clays and Post-G-lacial deposits are distiibuted "also throughout the 

 region generally. 



* The names given to these districts must not be taken in too limited a sense. The present 

 region is named as above, "because it is especially characterized, when viewed generally, by 

 the presence of carboniferous strata.
