428 DEEP MINING IN NOVA SCOTIA — PREST. 



be the more probable theory being- supported by testimony from 

 all parts of the Province. For example the fossiliferous, Oris- 

 kany, syncline of Bear River passes without a change of dip or 

 position into the granite on the west and re-appears with the 

 same fossils and dip and in the same range, a few miles further on 

 at Mistake Settlement, near the Sissibou. The eastern extension 

 of the same syncline passes into the granite to the east by the 

 same gradual metamorphism and re-appears to the south of 

 Annapolis town as a half metamorphic slate. The gold-bearing 

 leads and rocks of Mooseland pass in numerous places into the 

 granite, the lines of stratification gradually fading away as 

 crystallization increases. At Hubbard's Cove, Lunenburg Co., 

 the original bedding lines are distinguished for some distance 

 from the quartzite. To the gold miner one important result of 

 this period of metamorphic activity are the fractures caused by 

 the subse({uent shrinking of the fused districts. These are seen 

 at Sherbrooke, Mooseland, Mt. Uniacke, Newbern in Lunenburg 

 County and other places. 



To summarize some of the f oregfoino- notes, the events traceable 

 between the deposition of the auriferous rocks and their meta- 

 morphism, are as follows : — 



1st. Folding of the gold-bearing series. 

 2nd. Formation and mineralization of leads. 

 3rd. Formation of cleavage lines. 

 4th. Deposition of the Oriskany of Bear River. 

 5th. Farther folding of both series. 



This order may. nowever, be altered by a decisive solution of 

 the problem given on page 426. 



Denudation. 



Before enquiring into the results of erosion let us understand 

 thoroughly the condition of the surface before erosion began. 

 The upper strata, as far as denudation has left them, are the 

 bluish-grey slates, now seen at Lunenburg and the Sissibou 

 River. There may have been still higher strata (see page 423), 

 but the tremendous erosion to which the Province has been
