Tidge. The stratigrapHcal relation of the beds are much easier 

 determined here than in Sections 3034, 3035, or in 3036, and, as 

 i<hown in my horizontal section, the eastern limb of the syncline 

 of the quartzite band dips 35° westerly, and the strike is 10^ 

 west of mag. north. The quartzite folding round the superim- 

 posed clay-slate appears on the western side of the reserve, in 

 Section 722. As represented by horizontal section, it will be 

 seen that the anticlinal axis of the band and a considerable 

 portion of the subterimposed clay-slate have been carried away 

 by subsequent denudation, and that the actual dip side of the 

 quartzite band constitutes an integral part of the formation 

 about 20 chains to the east. The stone in this quarry, and 

 also in those situated in Sections 3036, 3035, and 3034, is 

 better adapted for road than architectural purposes. 



It is noteworthy that for a distance of over four miles we 

 have indubitable evidence of the occurrence of foldings nearly 

 parallel with the strike of the beds ; this by some might be re- 

 garded as being only on a small scale, but its presence suggests 

 the probable existence of others of greater magnitude hidden 

 from our observation; therefore a difficulty arises in cor- 

 rectly estimating the actual thickness of partially-concealed 

 strata. 



JEastern Quartzite Band. — The eastern quartzite band, as it 

 appears on the south bank of the South Para Biver, in Section 

 3281, north-western Para Wirra, makes the prominent land- 

 mark locally known as the Boar's Snout. This band, which is 

 here of vast thickness, constitutes the high ground to the west 

 of the deserted auriferous Miocene cement workings of Victoria 

 Hill, passes through mineral Section 426, where it has been 

 invaded transversely by denusive agency to such an extent as 

 to admit of the detritus of the auriferous cements on the 

 eastern side being carried some considerable distance to the 

 west. Passing immediately to the east of "Malcolm's Barossa" 

 Mine, it constitutes the high ground between that mine and 

 the alluvial diggings of Spike Gully; it intersects Cockatoo 

 Creek in Section 782, from thence through Sections 3021, 3022, 

 and 721. In Section 726, where also a quarry of road metal is 

 situated, the dip of the band is 68^ easterly, strike 5° west of 

 mag. north, thickness estimated from 60 to 80 feet. It is here 

 of medium hardness, and is composed of fine grains of quartz 

 held together by f el spathic paste, which being subject to decay 

 renders the stone somewhat too friable for road purposes.
