GEOLOGY OF MOOSE RIVER GOLD DISTRICT — WOODMAN. 87 



Fig. c. — Specimen taken from the roll of a vein ; show- 

 ing- the stratification curving beneath the roll, and 

 approximately parallel with it. About natural size. 

 Plate 9. Fig. a. — Section at intersection of middle fault with 

 south anticlinal axis of the subsidiary anticline ; on east 

 side of fault, in a small pit on area 71. Black band repre- 

 sents the hano-intr wall lead of Jo. Tavlor belt, chano-inp- 

 from a south dip, and leavino- the hanging wall whin. 



Fig. h. — In the same pit as fig. a ; section sliowing 

 fault. The lead is viewed along the strike, but has little 

 dip at this point. In these two figures, r/^ = glacial drift, 

 qt = quartzite, si = slate. 



Fig. c. — Section at the north end of trench 1 ; show- 

 ing crenulations in foot-wall lead of the Jo. Taylor belt 

 (vid. pi. 7, fig. a, north end of section). 

 Plate 10. View in quarry on area 77, looking northeast ; show- 

 ing on north side of quarry the eastward pitch of the 

 strata, and on the cast wall a fault plane (cf. ])1. 2) 

 Plate 11. Structural details. 



Fig. a. — Crenulated lead, just below Jo. Tajdor belt ; 

 to show relation between size of vein and anq^litude of 

 corrugation, and lack of sympathy of adjacent strata. 



Fig. b. — Serration of stratification by cleavage : quarry, 

 area 74. 



Fig. c. — Crenulated angular, Kaulback belt (cf. fig. a). 



Fig. (I. — Irregular vein ; west wall of quarry, area 73. 

 Inclined lines show cleavage, horizontal lines stratification. 



Figs, e, f. — Details of rhythmic crenulation of a lead. 



Fig. g. — Diagramatic section, to show the relation 

 between stratification, jointing, and cleavage, in the country 

 rock adjacent to a roll. Tne first follows the vein closely, 

 in full lines; the second is broadly curved, in full lines; 

 the third is but slightly curved, in broken lines. 



Fig. It. — Map of the middle fault, in the small pit at 

 east end of quarry, area 71.
