526 J. T. Jatson: 



is traced along Narrnieian Creek to the Yarra where, as before 

 noted, the strikes converge and one fold results, after which 

 the strike becomes north-east again. 



Associated with the niinor folds at Warrandyte are the con- 

 glomerates, grits and sandstones that have been already de- 

 scribed. These conglomerates and grits, wherever observed, are 

 conformable to shales and sandstones, and there is no evidence 

 of any unconformity between the beds, nor can any base be de- 

 tected. 



The outcrops of the conglomerates are numerous, and occur 

 on most of the folds, but the only distinctive one is that already 

 referred to. This is found on both sides of Whipstick Gully 

 and on the northern side of Anderson's Creek, folded round the 

 axis of the second minor anticline, and passing into Third Hill 

 and through Fourth Hill. 



The axis of the fold at Whipstick Gully has a strong pitch, 

 the crown of the conglomerate at the axial line being lower on 

 the northern side than on the southern. This pitch probably 

 accounts for its non-outcrop farther north. 



The conglomerate has a steep easterly leg and a more gentle 

 westerly one. thus illustrating the general nature of the main 

 fold. On the left side of Anderson's Creek, a disconnected band 

 of the conglomerate runs south-westerly parallel to the creek 

 for about 200 yards. Its outcrop ceases at the next tributary 

 gully ; but whether from faulting or from passing into finer- 

 grained rocks, cannot be stated. This band is, from the dips in 

 the vicinity, on the eastern leg of the anticline, but is not in a 

 direct line with that on the opposite side of the creek. The 

 western leg does not outcrop, but may be covered by alluvium 

 on the right bank of the creek. Faulting has probablv occurred 

 here, and caused a displacement of the conglomerate to the 

 east ; but it cannot be very much, as the axial lines of the anti- 

 cline continue southward with practically no deviation. 



This conglomerate has not been found on any of the other 

 folds. This may be due to faulting, or to occupying a small 

 area, or to a change in its lithological character, probably to 

 one of the two latter, as faulting on a large scale does not seem 

 to have much occurred.
