GEOLOGY OF MOOSE RIVER GOLD DISTRICT — WOODMAN. 41 



it is noticeable that the south syncline is one of low dips on 

 the whole, instead of the high dips prevailing to the west. The 

 south anticline has dips much like those in similar situations to 

 the west. 



Division iu : axial dips and plunges. — The southern and 

 subsidiar}^ anticlines are still pitching east. The former plunges 

 steeply immediately east of the fault, but flattens out after two 

 hundred feet are passed. The latter pitches 15° E. in the large 

 quarry, Q"" in the cut at the north of area 78, and 10'' in 

 the square quaiTy to the south. Hence it too is rapidly flatten- 

 ing. The axis of the north anticline dips 85^ S. The axes 

 of the compound subsidiary fold have not changed their attitude. 

 That of the syncline north of this fold dips 75° N., having 

 steepened somewhat. The axes of the south anticline and syn- 

 cline dip 78° S. and 82° S., respectively. 



Division iv : correlation with division Hi. — -Despite the 

 presence of the eastward plunge in the two southern anticlines, 

 which should bring newer beds to the surface eastward, the only 

 feasible interpretation of the structure, as represented by cross- 

 section (pi. 6), gives older strata at the surface. This is on the 

 basis (1) of the distribution of dips in the field, (2) of the 

 approximate equivalence of the Copper horizon with the Jo. 

 Taylor belt. There is so much change that on the subsidiaiy 

 fold the Jo. Taylor belt would be 260 to 270 feet above the 

 present surface. 



The folds have not changed their character materially, but 

 their relative positions are altered. The north anticline is still 

 broad, and the local anticline is still close to the sharp 

 south main fold. But the distribution of dips in the field places 

 the north synclinal axis much nearer the north anticline, so 

 that, althougii the dips on the south side of the syncline are low, 

 the strata rise considerably upward. It is this that brings the 

 liorizon of the Copper lead, or its equivalent the Jo. Taylor belt, 

 so far above the present surface at the crest of the south main 

 a.nticline.
