GEOLOGY OF MOOSE RIVER GOLD DISTRICT — WOODMAN. 35 



Division ii: luestiuard "pitch of north anticline. — Many- 

 years ago the Big North was sloped out on the crest of the fold 

 westward on a plunge, the work going somewhat farther than 

 the shaft at the north end of area 132, or about 200 feet. Later 

 the crown was broken down in part, and the present quarry 

 made. This plunge, characteristic of most of the gold districts 

 of Nova Scotia, begins on the east side of area 131 at 9.5° W., 

 and becomes 12° on the west side of the same area. How much 

 higher the angle grows it is impossible to say ; for the west fault 

 cuts off both the Big North and Serpent loads, and it has never 

 been proved that the leads west of the break are the same. 



Division ii : siihsidiary fold, pitching east.— ^o\xi\\ of the 

 anticlinal axis in areas 130 and 131, the only dip except on the 

 plunge comes fi'om a trial shaft in the center of area 130. Here 

 slate was encountered, almost flat, but dipping south enough to 

 give an average of 5° S. According to this, the axial plane dips 

 70° S. in this part of the fold. At the south end of these areas 

 is the Archibald vein. This dips 48° S. at the surface ; but it 

 does not lie directly in the bedding, as witness the discordance 

 of its strike .with all the others near. The Bruce is, however, 

 " regular " or interstratified. From it to the south end of areas 

 70 and 71 the structure, revealed only by the quarry, gives folds 

 merely foreshadowed in division i. The dips are south for sixty 

 to eighty feet south of the Bruce belt (pi. 7 fig. c) ; but the 

 strike is erratic, varying from the normal — almost east and 

 west — at the north, to N. 20° E. in one place at the south. For 

 thirty feet farther the dips are slightly northward, the strikes 

 varying from N. 10° W. to N. 30' W. Here, then, is a local 

 syncline, apparently dying out westward, and running east to 

 the fault. That part of division i (pi. 3) to which it corresponds^ 

 is" the flattening out of the south dips in the Alex. Taylor lead 

 and vicinity. The best estimate of the dip of the axial plane 

 makes it 83 N. 



The anticline south of this trough corresponds to the change 

 from low to high dips toward the Britannia, in division i. It
