40 GEOLOGY OF MOOSE RIVER GOLD DLSTRICT — V.'OODMAN. 



Tlie latter is low, instead of resting liigh on the bulging side of 

 the former ; and the main fold is therefore much steeper on its. 

 south side. The south anticline remains nearly the same as. 

 in the other two divisions, its axis here dipping 85" S. Tho 

 syncline to the north of it apparently dips 80° S. 



The subsidiary fold is better developed than in division 

 ii. Its axes all dip 85° N. Since the bulge on the south side of 

 the north anticline is hypothetical to some extent, having only 

 one exposure for direct evidence, it is difficult to give its axial 

 dip.. The structure is best explained, however, by an inclination 

 of 70° N. for the axis of the syncline south of the bulge. Had 

 the section been made near the eastern side of the block instead 

 of the western, the south anticline would be found to have 

 pitched down to a somewhat lower level, with reference to the 

 others. The axial plane of the north anticline dips 85° S. 



Division iv. — In many ways division iv is not so well 

 known as the two to the west. The openings are fewer, shal- 

 lower, and for the most part in disuse. At the critical portion, 

 however, a large quarry has been opened, and two smaller ones 

 to the east. North of the Little North there has been almost 

 no prospecting. Between this and the North Sutherland the 

 rock is largely slate, and south of the latter is practically 

 all vslate to the Miller lead. 



Division iv : subsidiary and south anticlines.- — The only 

 dips north of the axis of the north anticline are the three leads 

 given on the map, and considered by those who worked them in 

 earlier years to be the equivalents of leads of the same name 

 west of the fault. South from the axis are, or have been, a 

 number of exposures with leads, now for the most part aban- 

 doned. All were cut very shallow, and information regarding 

 them is hard to get. The new quarry on areas 76 and 77, 

 lying along the middle anticline, gives the same structure as in 

 corresponding parts of division iii ; but the southernmost of the 

 axes is farther from the center of the sag. The rock here 

 is a black lustrous slate with a few green bands. To the south
