GEOLOGY OF MOOSE RIVER GOLD DISTRICT — WOODMAN. 39 



ently rises slowly, for in one place slate lies horizontal ; and at 

 the axis of the anticline the lead comes up at an angle of 30°, 

 over a thin stratum of whin which underlies the belt. At the 

 trench this is narrow, and the lead is seen descending the south 

 side at an average angle of 10° but " rolling " heavily. Near 

 the south end of the trench the hanging wall lead has a dip of 

 5° S., but becomes steeper within a few feet. It is overlain by 

 the same quartzite which is seen in the quarry to the west, and 

 above this lies the Ferguson, a lead which at the south edge of 

 the quarry occupies a similar position. A feature of these ex- 

 posures is the easterly pitch of the beds, continued from the area 

 west of the fault. The foot- wall lead plunges east lO"", and 

 the hanging wall 5°, where seen. 



The south trench gives an almost continuous series of dips. 

 The greater steepness of the rocks, compared with observations 

 farther east, has already been noted. The axis of the south 

 anticline is determinable in this trench precisely. At a distance 

 152 feet south of the north end of the trench, a ledge appeared 

 in 1899 to give both north and south dips. Although only two 

 and one-half feet broad at the base, it had a dip of 50° N. 

 on the north, and a steep south dip on the south side. Blasting 

 revealed an arched lead, showing the exact position of the axis 

 <pl. 11, fig. i). 



Division Hi: interpretation, and correlation ivith div. H. — 

 In interpretating the data in this block in terms of a structural 

 •section, tw^o points must be emphasized. One is that in 300 feet 

 north from the quarry on areas 73 and 74, there is but one ex- 

 posure : the other relates to the interpretation of division ii. 

 There, upon what appear to be safe and adequate grounds, 

 a, structure is worked out which makes the Taylor belt a horizon 

 •equivalent to the Copper belt, or strata very close to it. The 

 former is found again in division iii ; and if the interpretation is 

 ■correct, the equivalence must be continued. This shows a 

 •change of shape to have taken place in the north anticline, and 

 in the position of the subsidiary fold with reference to it (pi. 5).
